Wherein, control result well whether determination unit 6 use real data Si and reality from control object complete equipment 1 Border data previous value Si0 and judging whether well stored in database DB4 it is good whether judge that data S5, judgement are practical Data Si towards good direction change still towards the direction change of deterioration, output control result well whether data S6.
In learning data preparing department 7 in control method learning device 21, using will be made by control executive device 20 The control operating side operational order S2 that goes out, control operating quantity S3, the output of control operating quantity could the input datas difference such as data S4 Postpone same time obtained from data and from control result well whether determination unit 6 control result well whether data S6 is produced on the new teacher data S7a used in the study of neural network, is supplied to control rule learning portion 11.In addition, religion Teacher's data S7a is data corresponding with the regular control operating side operational order S2 of the output of enforcement division 10 of control, learning data system Make portion 7 can will use control result well whether determination unit 6 control result that provides well whether data S6 speculate control Data find out as new teacher's data S7a obtained from the control operating side operational order S2 that regular enforcement division 10 exports.
Fig. 3 shows the concrete structure example in the control rule learning portion 11 of the embodiment of the present invention.Control rule learning portion 11 be by input data preparing department 114, teacher's data creating portion 115, Processing with Neural Network portion 110, neural network selector 113 It is constituted as main structural element.In addition, in control rule learning portion 11, as from external input, obtain Make data S8a made of the input data S1 delay times from input data preparing department 2, obtains coming from learning data preparing department 7 new teacher data S7a, referring additionally to the number put aside in controlling rule database DB1 and learning data database D B2 According to.
In control rule learning portion 11, by input data S1 via input data after compensation reasonable time delay Preparing department 114 is taken into Processing with Neural Network portion 110.
In addition, in control rule learning portion 11, new teacher's data S7a from learning data preparing department 7 is made to teach It is the total religion for further including the past teacher's data S7b for being stored in learning data database D B2 in teacher's data creating portion 115 Teacher's data S7c and be supplied to Processing with Neural Network portion 110.These teacher's data S7a, S7b are suitably stored in learning data Database D B2 and utilize.
Similarly, the input data S8a from control input data preparing department 2 is made to be in input data preparing department 114 Further include the total input data S8c for the past input data S8b for being stored in learning data database D B2 and is supplied to god Through network processes portion 110.These input datas S8a, S8b are suitably stored in learning data database D B2 and are utilized.
Processing with Neural Network portion 110 is made of neural network 1 11 and neural network lea rning control portion 112, neural network 1 11 Be taken into the input data S8c from input data producing device 114, teacher's data S7c from teacher's data creating portion 115, The control that neural network selector 113 is selected is regular (neural network), and the neural network that will eventually determine is stored in control rule Then database D B1.
Neural network lea rning control portion 112 is for input data producing device 114, teacher's data creating portion 115, nerve net Network selector 113, with timing controlled appropriate they and obtain the input of neural network 1 11, in addition control is by handling result It is stored in control rule database DB1.
Here, neural network 1 01 in the control executive device 20 of Fig. 2 and in the control method learning device 21 of Fig. 3 Neural network 1 11 is all the neural network of same concept, when to being illustrated using the difference in upper basic conception, such as with It is lower described.First, the neural network that the neural network 1 01 in executive device 20 is predetermined content is controlled, is being provided The control operating side operational order S2 as corresponding output is found out when input data S1, it may be said that be used in a direction The neural network of processing.In contrast, neural network 1 11 in control method learning device 21 is used for will be about input data Input data S8c, the teacher's data S7c of S1 and control operating side operational order S2 are set as asking by learning when learning data Go out to meet the neural network of its input/output relation.
The considerations of basic handling in control method learning device 21 formed as described above, method was as described below.It is first First, control operating quantity output could data S4 content be "available" in the case of, to control object complete equipment 1 export control Operating quantity exports SO, control result well whether data S6 content be that " good " (real data Si becomes towards good direction Change) in the case of, judge that the control operating side operational order S2 that regular enforcement division 10 exports in order to control is correct, so that neural network Be output into control operating side operational order S2 mode make learning data.
On the other hand, control operating quantity output could the content of data S4 be "No" in the case of, or to control The output of object complete equipment 1 control operating quantity output SO and control result well whether data S6 content be "No" (actual number According to Si towards the direction change of deterioration) in the case of, judge the control operating side operational order that regular enforcement division 10 exports in order to control Mistake occurs for S2, and learning data is made in a manner of the not output of output nerve network.At this point, being exported as control, with opposite Identical control operating side output+direction, this 2 kinds of-direction mode exported constitute neural network output, with what is do not exported The mode of the control operating side operational order S2 of side makes learning data.
In addition, in the control rule learning portion 11 that Fig. 3 is illustrated, as the number based on neural network lea rning control portion 112 According to processing as a result, processing as described below.Here, first used as make to control executive device 20 input data S1 prolong The learning data of the combination of S8c obtained from the slow time and the teacher's data S7c produced by teacher's data creating portion 115, it is real It is applied to the study of the neural network 1 01 of control rule enforcement division 10.In fact, having and controlling in control rule learning portion 11 The 01 identical neural network 1 11 of neural network 1 of system rule enforcement division 10 carries out performance test to learn this under various conditions When response, the result as study be confirmed generate more good result control rule.Due to needing using multiple Learning data is learnt, so taken out from the learning data database D B2 for having put aside the learning data produced in the past This learning data is stored in learning data database D B2 by multiple past learning datas to implement study processing. In addition, learn the neural network is stored in control rule database DB1 to be utilized by the regular enforcement division 10 of control.
In the study of neural network, both past learning data can together be made whenever making new learning data For learning, past learning data can also together be made after by learning data savings to a certain degree (such as 100) For learning.
In addition, control result well whether determination unit 6 in, according to from well whether judge that database DB4's is good Whether determinating reference, judge whether implementing good.Control result it is good whether judge, due to being sentenced according to control purpose Disconnected result is different, so multiple neural networks corresponding with multiple control purposes are made, even if input data is identical also according to control Purpose processed makes teacher's data to learn respectively, to make multiple teacher's data for the input data of 1 secondary amounts and be used for The study of the corresponding neural network of each teacher's data, thus, it is possible to study nerve nets corresponding with multiple control purposes simultaneously Network.Here, multiple control purposes refer to, such as want any part is preferentially controlled on plate width direction in the case where shape controls (plate end, central portion, asymmetric portion etc.) thinks preferentially to control multiple control object projects (such as plate thickness and tension, rolling lotus Arbitrary project etc. in again etc.).
In the case where being configured to as described above, once the neural network 1 01 for controlling regular enforcement division 10 is learned When habit, new control operation is not just implemented.Therefore, make new operating method random in due course using control operation interference generating unit 16 Ground occurs, and is applied to control operating quantity S3 and carrys out executive control operation, to learn new control method.
Hereinafter, being controlled as object with the shape in sendzimir mill shown in patent document 1, this whole series is described in detail and sets Standby control method.In addition, being controlled about shape, illustrated using following specifications A, B.
Specification A is the specification about priority, is set as the information with the priority of plate width direction.For example, in shape control In system, it is desired value that the control on entire plate width direction is often difficult in mechanical property.Therefore, under being arranged on plate width direction State 2 specifications A1, A2 about priority.Wherein, it is " keeping plate end preferential " about the specification A1 of priority, about priority Specification A2 be " keeping central portion preferential ", implement according to 2 orders of priority as A1, A2 control.In the feelings for implementing control Under condition, consider about any specification in the specification A1 or A2 of priority.
Specification B is the specification for the condition distinguished in advance about reply.If given an example, shape model and control The relationship of method due to changing under various conditions, so be considered needing for example by by specification B1 be set as plate it is wide, by specification B2 is set as the division of steel grade class to separate.It is changed respectively due to above-mentioned, so the influence journey of the shape to shape manipulation end Degree changes.
In the example, control object complete equipment 1 is sendzimir mill, and real data is shape actual result.This Outside, sendzimir mill is the milling train with multiple roll for carrying out cold rolling to the hard material such as stainless steel.It is rolled in Sendzimir In machine, in order to provide hard material the working roll for rolling and using by force path.Therefore it is difficult to obtain flat steel plate.As Its countermeasure, using the constructing of multiple roll, variously-shaped control unit.In sendzimir mill, it is however generally that, among the upper and lower the 1st Roller has single cone, other than it can shift, also have 6 segmentation rollers and 2 rollers for being referred to as AS-U up and down.In following explanation Example in, as the real data Si of shape, using the detection data of shape detector, and then as input data S1, make It is used as and the form variations of the difference of target shape.In addition, as control operating quantity S3, it is set as the AS-U, upper and lower of #1~#n The roller amount of movement of 1st intermediate calender rolls.
Fig. 4 shows the neural network structure in the case of use in the control of the shape of sendzimir mill.Here, conduct Neural network is neural network 1 01 when for controlling regular enforcement division 10, and god is indicated when for controlling rule learning portion 11 Through neural network shown in network 111, but construct all identical.
In the example of the shape control of sendzimir mill shown in Fig. 4, the reality from control object complete equipment 1 Data Si be include that (form variations for being set as the difference as true form and target shape herein are defeated for the data of shape detector The data gone out) the real data of sendzimir mill, as input data S1, obtained in control input data preparing department 2 Standardized form deviation 201, form variations grade 202.The input layer of neural network 1 01,111 is inclined by standardized form as a result, Poor 201, form variations grade 202 is constituted.In addition, in Fig. 4, form variations grade 202 is used as to neural network input layer Input, but neural network can also be switched according to grade.
In addition, output layer and the shape as sendzimir mill control the AS-U of operating side, the 1st intermediate calender rolls accordingly by AS-U operational degrees 301 and the 1st intermediary operation degree 302 are constituted.In respective operational degree, about AS-U, for each AS- There is U AS-U evolutions to close direction (roll gap closing to (roll gap (interval between the roller of operation up and down of milling train) open direction), AS-U Direction).In addition, about the 1st intermediate calender rolls, have the 1st intermediate calender rolls evolution to (the 1st intermediate calender rolls are to roll upper and lower 1st intermediate calender rolls The direction that machine center is acted towards outside), the 1st intermediate calender rolls close direction (direction that the 1st intermediate calender rolls are acted towards milling train central side). For example, in the case where shape detector is 20 subregions and form variations grade 202 is set as 3 grade (large, medium and small), Input layer is 23 inputs.In addition, AS-U seat board be 7 pieces and upper and lower 1st intermediate calender rolls can when being shifted on plate width direction, Output layer is the 18 total of 14 AS-U operational degrees, 301,41 intermediary operation degree.In time set the number of plies of middle layer And the neuron number of each layer.Although in addition, carrying out aftermentioned, the shape about the sendzimir mill as output layer with reference to Fig. 8 Operating side is controlled, it is defeated to be constituted neural network in a manner of relatively each control operating side output+direction, the output of this 2 kinds of-direction Go out.
Figure 10 shows form variations and control method.Here, on the top of Figure 10, show in the case where form variations are big Control method the control method in the case where form variations are small is shown in the lower part of Figure 10.In addition, short transverse is shape The size of shape deviation, X direction are plate width direction, the wide both sides display plate end of plate, central display plate central portion.Such as figure It is preferential to correct entirety compared to the form variations of the part of plate width direction in the case where form variations are big shown in 10 top Shape.On the other hand, as shown in the lower part of Figure 10, in the case where form variations are small, the preferential form variations for reducing part.
As such, it is desirable to according to the size modification control method of form variations, so setting form variations grade as shown in Figure 4 202 and it is supplied to neural network 1 01,111, the size of predicting shape deviation.About form variations, no matter the size of form variations How, such as all using the result for being standardized as 0~1.This is an example, both it is contemplated that not carried out to form variations The input layer of neural network is standardized and is directly inputted to, it is also contemplated that certainly according to the big minor change neural network of form variations Body (such as prepares 2 neural networks, distinguishes the neural network that is used in the case where form variations are big and small in form variations In the case of the neural network that uses).
So that neural network 1 01,111 study described above such as the structure of Fig. 4 is directed to the operating method of shape model, makes Implement shape control with the neural network learnt.It, also can be according to learning even mutually isostructural neural network Condition and different control output is exported with different characteristic and for same shape pattern.
Therefore, multiple neural networks are used separately by the other conditions according to shape real data, can be directed to each Kind condition constitutes best control.This is the correspondence for specification B.The representation of previously described Fig. 2 carries out above-mentioned specification In the case of concrete example.In the structural cases of Fig. 2, for the neural network 1 01 for controlling regular enforcement division 10, according to The individual neural networks of preparations such as actual conditions, mill personnel's name, the steel grade class of material to be rolled, plate be wide are rolled, are registered To control rule database DB1.In neural network selector 102, the neural network of selection and the condition coupling at the time point And set the neural network 1 01 of regular enforcement division 10 in order to control.In addition, as the time point in neural network selector 102 Condition, the wide data of plate can be taken into from the real data Si in control object complete equipment 1, correspondingly selection god Through network.In addition, if multiple neural networks as used herein have input layer as shown in Figure 4, output layer, middle layer The number of plies, the unit number of each layer can also be different.
Fig. 7 shows to make data S1 (the standardized form deviations of the input layer for being input to neural network 1 01,111 201, form variations grade 202) control input data preparing department 2 summary.Here, as real data Si, detection is controlled Plate shape when object complete equipment 1 processed is the rolling in sendzimir mill, the shape detector data of shape detector As input, the testing result as each shape detector subregion is found out first with form variations PP values arithmetic unit 210 Form variations PP values (Peak To Peak values, peak-to-peak value) S of the difference of maximum value and minimum valuePP.It is transported in form variations grade It calculates in device 211, according to form variations PP values SPPForm variations are classified as this large, medium and small 3 grades.Shape is rolled The plate width direction of the elongation of material is distributed, and the I-UNIT office of elongation will be indicated with 10-5 units.For example, such as following formula Classify like that.
Here, classifying as follows:By the establishment of (1) formula, form variations grade become (it is big=1, in=0, small= 0), by the establishment of (2) formula, form variations grade become (it is big=0, in=1, small=0), by the establishment of (3) formula, shape is inclined Poor grade become (it is big=0, in=0, small=1).In addition, form variations about each subregion herein, using being set as SPM=SPP's SPMCarry out execution standardization.

As previously discussed, the standardized form deviation 201 and shape as the input data to neural network 101 are made Deviation levels 202.Standardized form deviation 201 and form variations grade 202 are the input datas of control rule enforcement division 10 S1。
Fig. 8 shows the summary of control output operational part 3.Control output operational part 3 is according to from control rule enforcement division 10 The output of interior neural network 1 01 is to control operating side operational order S2 (in the example of the shape control of sendzimir mill AS-U operational degrees 301, the 1st intermediary operation degree 302 are suitable with its), it makes as the operation for controlling operating side to each shape The control operating quantity S3 of instruction.In addition, herein about there are multiple AS-U operational degrees 301, the 1st intermediary operation degree 302, Show that each 1 data example, each data are constituted from evolution to degree with a pair of of the data for closing direction degree.
In control output operational part 3, the AS-U operational degrees 301 of input have each AS-U evolutions to, close the defeated of direction Go out, so being multiplied by conversion gain G by the difference to themASUTo export the operational order to each AS-U.Due to the control to each AS-U System output is the positions AS-U amount of change (unit is length), so conversion gain GASUIt is the transformation from degree to position amount of change Gain.
In addition, the 1st intermediary operation degree 302 equally inputted has the output of outside, inside among the 1st, so passing through Conversion gain G is multiplied by their difference1STTo export the operational order shifted to each 1st intermediate calender rolls.Due to each 1st intermediate calender rolls Control output be the 1st intermediate calender rolls shift position amount of change (unit is length), so conversion gain G1STIt is from degree to position The conversion gain of amount of change.
By the above, being capable of operation control operating quantity S3.Operating quantity S3 is controlled by the positions #1~#nAS-U amount of change (n bases In the seat board number of AS-U rollers) and upper 1st intermediate bit position amount of change, lower 1st intermediate bit position amount of change composition.In addition, In fig. 8, it is illustrated that the interference data from control operation interference generating unit 16 are applied to control operating side operational order S2 System.
Fig. 9 shows the summary of control output determination unit 5.Control output determination unit 5 is repaiied by rolling phenomenon model 501 and shape Determination unit 502 is constituted whether just good, is obtained the real data Si from control object complete equipment 1, is exported fortune from control The information of the control operating quantity S3 and output judgement database DB3 in calculation portion 3, the control operating quantity provided to control operating side are defeated Going out could data S4.By above structure, in control exports determination unit 5, by the way that the control for exporting operational part 3 and calculating will be controlled The variation of shape in the case that operating quantity S3 processed is output to the milling train as control object complete equipment 1 is input to known control The model (in the case of the embodiment of fig. 9 be rolling phenomenon model 501) of object complete equipment 1 processed is predicted, pre- Want in the case of deteriorating for shape, inhibits control operating quantity to export SO, prevent shape from substantially deteriorating.
If described in more detail, control operating quantity S3 is input to rolling phenomenon model 501 to predict based on control The change in shape of operating quantity S3, operation form variations correction amount prediction data 503.On the other hand, by coming from control object The shape detector data Si (the form variations real data 504 of current point in time) of complete equipment 1 is added form variations amendment It measures prediction data 503 and obtains form variations prediction data 505, by evaluating form variations prediction data 505, can predict How shape changes when control operating quantity S3 is output to control object complete equipment 1.According to the form variations actual number of present situation According to 504 and form variations prediction data 505, whether shape corrects good in determination unit 502 predicting shape towards good direction Towards the direction change of deterioration, obtaining control operating quantity output could data S4 for variation or shape.
Whether shape corrects good in determination unit 502, specifically carry out as described below shape it is modified well with No judgement.First, as shown in specification A1, A2 of the priority controlled about shape, consider the control priority on plate width direction, So the weight coefficient w (i) of plate width direction is set to each specification of specification A1, specification A2 in output judgement database DB3.Make With its, such as using following (4) formulas evaluation function J come predicting shape variation it is good whether.In addition, in (4) formula, w (i) it is weight coefficient, ε fb (i) are that practical 504, the ε est (i) of form variations are that form variations predict that 505, i is shape detector Subregion, rand are random several.
[Formula 4]
In the case of the evaluation function J of use (4) formula, when evaluation function J deteriorates into just, shape becomes when shape becomes good Evaluation function J is negative.In addition, rand is random several, the evaluation result of evaluation function J is made randomly to change.Even if existing as a result, In the case that shape deteriorates, still there is the situation for becoming positive as evaluation function J, so not about rolling phenomenon model 501 Correct situation can also learn the relationship of shape model and control method.Here, in the control object as test running originally Increase maximum value in the case of the model of complete equipment 1 is insecure, want to implement stable control with certain degree learning control method The mode that 0 is set as in the case of system in time changes rand.
Whether shape corrects good in determination unit 502, operation evaluation function J, to be set as control operating quantity in J >=0 Output could data S4=1 (can), in J<Be set as when 0 control operating quantity output could data S4=0 (no) mode, output control Operating quantity output processed could data S4.
In control exports suppressing portion 4, exported according to the control operating quantity of the judgement result as control output determination unit 5 Could data S4, determining has undirected control object complete equipment 1 output control operating quantity output SO.Controlling operating quantity output could Data S4 is the amount of change output of the positions #1~#nAS-U, the output of upper 1st intermediate bit position amount of change, lower 1st intermediate bit position Amount of change output is set, determination of such as getting off is passed through.
IF (control operating quantity output could data S4=0) THEN
The positions #1~#nAS-U amount of change output=0
Upper 1st intermediate bit position amount of change output=0
Lower 1st intermediate bit position amount of change output=0
ELSE
The positions the #1~#nAS-U amount of change output=positions #1~#nAS-U amount of change
Upper 1st intermediate bit position amount of change exports=upper 1st intermediate bit position amount of change
Lower 1st intermediate bit position amount of change exports=descends the 1st intermediate bit position amount of change

In controlling executive device 20, according in the real data Si execution of control object complete equipment 1 (milling train) Operation is stated, control operating quantity output SO is output to control object complete equipment 1 (milling train), to implement shape control.
Next, illustrating the action summary of control method learning device 21.In control method learning device 21, using The time delay data of the data used in control executive device 20.Time delay Z-1Mean e-TS, indicate that delay is preset Time T.Control object complete equipment 1 has time response, so being sent out in real data according to control operating quantity output SO Changing is previously present time delay.Therefore, using the reality at the time point for passing through delay time T after executive control operation Data are implemented to learn.In shape control, detected to shapometer after being exported for the operational order of AS-U, the 1st intermediate calender rolls Until change in shape, several seconds are needed, it is possible to which being set as T=2 to 3 seconds or so, (delay time is also according to shape detector Type, mill speed and change, as long as so will control operating side change become change in shape until the best time It is set as T).
Figure 11 shows the action summary of determination unit 6 whether control is good.Change in shape well whether determination unit 602 in make With following formula it is good whether judge evaluation function JC
[Formula 5]
In addition, in (5) formula, ε fb (i) are the form variations real data for including, ε last (i) in real data Si It is form variations real data previous value, the plate width direction weight coefficient of judgement whether wC (i) is good.Here, based on good Database DB4 is judged whether good, according to the weight system of specification A1, A2 of the priority about control setting judgement whether good Number wC (i).Using well whether judge whether evaluation function Jc judgement control result good.In addition, being exported about as control The control operating quantity output of the judgement result of determination unit 5 could data S4 the case where being 0 (control output can not), although it is practical to The control operating quantity output=0 of control object complete equipment 1, but still it is judged as that shape deteriorates.
Here, control operating quantity output could data S4=0 in the case of, data S6 whether being set as control result well =-1.In addition, according to threshold condition (LCU >=0 >=LCL), preset threshold value upper limit LCU and threshold value add and subtract LCL.At this point, with Judge the result of the comparison of evaluation function Jc if it is Jc&gt whether good;LCU, then data S6 whether being set as control result well =-1 (shape deterioration), if it is LCU >=Jc >=0, then (shape is towards deterioration by data S6=0 whether being set as control result well Direction change), if it is 0>Jc >=LCL, then (shape becomes data S6=1 towards good direction whether being set as control result well Change), if it is Jc<LCL, then data S6=0 whether being set as control result well (shape is good).
Here, control result well whether data S6=-1 indicate to inhibit exported control output since shape deteriorates The case where, control result well whether data S6=0 indicate since amorphism variation or shape are good and keep being exported The case where control output, although control result well whether data S6=1 indicate that shape has towards good direction change into one The case where step becomes good possibility and exported controlled quentity controlled variable is made to increase.
In this way, according to specification A1, A2 of the priority about control, the weight coefficient wC (i) of plate width direction changes, Judge that evaluation function Jc is different whether so good.Therefore, the judgement result of data S6 whether being considered control result well It is different.Therefore, in control method learning device 21, control knot is implemented to this 2 kinds of specification A1, A2 of the priority about control Fruit well whether data S6 judgement.
Next, illustrating the summary of learning data preparing department 7.As shown in Figure 1, in learning data preparing department 7, according to next The judgement result (control result well whether data S6) of determination unit 6 whether from control result well utilizes control operating side behaviour The judgement result (output of control operating quantity could data S4) for making instruction S2, control operating quantity S3, control output suppressing portion, makes For teacher's data S7a of the neural network 1 11 used in control rule learning portion 11.
Teacher's data S7a of the situation is output, that is, AS-U operations of the output layer shown in Fig. 4 from neural network 1 11 Degree 301,1 intermediary operation degree 302.Control operating side of the learning data preparing department 7 used as the output of neural network 1 01 Operational order S2 (AS-U operational degrees 301,1 intermediary operation degree 301) and #1~#nAS- that SO is exported as control operating quantity The amount of change output of the positions U, the output of upper 1st intermediate bit position amount of change, the amount of change output of lower 1st intermediate bit position, make For teacher's data S7a of the neural network 1 11 used in control rule learning portion 11.
In the action summary for illustrating learning data preparing department 7, by each section number in the control output operational part 3 of Fig. 8 It is Figure 12 to be arranged according to the relationship of, mark.Here, the control operating side operational order S2 about the output as neural network 1 01, AS-U operational degrees 301 are representatively shown, the data of operational degree positive side are set as OPref, by the number of operational degree negative side According to OMref is set as, the operational degree occurred at random from control operation interference generating unit 16 is set as operational degree random number Conversion gain is set as G by Oref, and control operating quantity output SO is set as Cref and is illustrated.In this way, herein to put it more simply, The output of the output layer of neural network 1 01 from control rule enforcement division 10 is set as operational degree positive side and operational degree The operational degree occurred at random from control operation interference generating unit 16 is set as operational degree random number by negative side.In addition, will It is set as operational order value for the control operating quantity output SO of control operating side.
Figure 13 shows the processing step in learning data preparing department 7 and process content.Here, if according to Figure 12 mark Agreement illustrate, then utilize (6) formula to find out operational order value Cref in initial processing step 71.
[Formula 6]
Cref=G (OPref-OMref+ORref) ... (6)
In next processing step 72, whether according to control result well data S6 correct operational order value Cref and It is set as C ' ref.Specifically, control result well whether data S6=-1 when utilize (7) formula, control result well whether When data S6=0 utilize (8) formula, control result well whether data S6=1 when utilize (9) formula, be set as operational order value Correction value C ' the ref of Cref.
[Formula 7]
[Formula 8]

[Formula 9]
In processing step 73, according to revised operational order value C ' ref, (10), (11) formula is utilized to find out operation journey Spend correction amount Oref.
[Formula 10]
C ' ref=G ((OPref+ Δ Oref)-(OMref- Δ Oref)) ... (10)
[Formula 11]
In processing step 74, (12) formula of utilization finds out teacher's data OP ' ref, OM ' ref for neural network 1 11.
[Formula 12]
In this way in learning data preparing department 7, as shown in figure 12, control object complete equipment 1 is exported for reality Operational order value Cref, the control result of judgement result whether according to as control result well in determination unit 6 well whether Data S6, arithmetic operation command value correction value C ' ref.Specifically, control result well whether data S6=1 the case where Under, control direction is OK, but insufficient in the case that judging to export in order to control, and operational order value is made to increase Δ to the same direction Cref.Conversely, control result well whether data S6=-1 in the case of, be judged as control direction there is a situation where mistake Under, so that operational order value is reduced Δ Cref round about.Conversion gain G is known, institute due to being preset With if it is known that operational degree positive side and the value of operational degree negative side, then can find out correction amount Oref.Here, sharp in advance Value appropriate is found out with emulation etc. to set Δ Cref.By above step, it can be found out and controlled using above-mentioned (12) formula Teacher's data OP ' ref, the OM ' ref used in rule learning portion 11.
In addition, being illustrated in fig. 13 with simple example, but actually implement the AS-U for #1~#nAS-U The whole of operational degree 301 and the 1st intermediary operation degree 302 shifted for the displacement of upper 1st intermediate calender rolls, lower 1st intermediate calender rolls, Teacher's data of the neural network 1 11 used in control rule learning portion 11 are set as (in AS-U operational degree teachers data, 1 Between operational degree teacher data).
Figure 14 shows the data example preserved in learning data database D B2.For learning neural network 111, need to be permitted The combination of multi input data S8a and teacher's data S7a.Therefore, the teacher's data S7a that will be produced by learning data preparing department 7 (AS-U operational degree teachers data, the 1st intermediary operation degree) and control rule execution is input in controlling executive device 20 The time delay data S8a of the input data S1 (standardized form deviation 201 and form variations grade) in portion 10 is combined and is made For one group of learning data, it is saved in learning data database D B2.
In addition, various database D B1, DB2, DB3, DB4, Figure 15 is used to show in the complete equipment control device of Fig. 1 Structure for the neural network management table TB for being associated ground management application to each database D B1, DB2, DB3, DB4.Pipe Reason table TB has the management table of specification.Specifically, in management table TB, according to (B1) plate wide, (B2) steel grade class with And specification A1, A2 of the priority about control divides specification.It is wide as (B1) plate such as wide using 3 feet, meter is wide, 4 Foot is wide, 5 feet wide this 4 divisions use steel grade class (1)~steel grade class (10) this 10 to divide degree as steel grade class.Separately Outside, for the specification A of the priority about control, it is set as this 2 kinds of A1 and A2.In this case, 80 divisions are set as, according to Rolling condition is used separately 80 neural networks.
