Abstract
The invention relates to a control adjustment method of load distribution of a work speed of a paper machine speed chain. A PLC is taken as a load distribution controller, through a DeviceNet bus, the torque of each frequency converter is read into the PLC, and the torque is compared through calculation by use of a PID algorithm. The method provided by the invention mainly has the following advantages: since a paper machine transmission system has high requirements for rapidness, accuracy and stability, the load distribution can be changed at any time according to a load condition, a comparison is made with actual torque of each motor according to a flat expected torque, calculation is carried out by use of the PID algorithm, and optimal distribution is realized.
Description
Technical field
The present invention relates to a kind of control and regulation method of sharing of load of operating rate of paper machine speed chain.
Background technology
In the transmission system of paper machine, often run into the situation that several motors drag same load simultaneously, for example: the suction couch roll of wet end and drive net roller and be with a net simultaneously, of this sort transmission only has the job requirement that synchronously can not meet real system of motor, in real work, also require each drive station load-rate of motor identical, otherwise it is excessive to there will be a motor to exert oneself, another motor little situation of exerting oneself.
Summary of the invention
The object of the present invention is to provide a kind of control and regulation method of sharing of load of operating rate of paper machine speed chain. For achieving the above object, the technical solution used in the present invention is: a kind of control and regulation method that the present invention relates to sharing of load of operating rate of paper machine speed chain, the control and regulation method of the sharing of load of the operating rate of a kind of paper machine speed chain described in it is characterized in that is using PLC as Control System of Load Distribution device, by DeviceNet bus, the torque of each frequency converter is read in PLC, the relatively employing pid algorithm of torque calculates, and its computing formula is。
Advantage of the present invention is mainly reflected in：
Driving system of paper machine requires fast, accurate and stable, changes at any time so sharing of load can be followed loading condition, compares according to the flat torque of expecting torque and each motor reality, adopts pid algorithm to calculate, and reaches optimal allocation.
Detailed description of the invention explanation
Tell about a kind of course of work of control and regulation method of sharing of load of operating rate of paper machine speed chain below:
Using PLC as Control System of Load Distribution device, by DeviceNet bus, the torque of each frequency converter is read in PLC, determine master control frequency converter by sharing of load, the output torque of the torque of main frame and slave frequency converter is compared, adjust in real time the output frequency of frequency converter, by repeatedly automatically adjusting, reach balancing the load and distribute, complete sharing of load function.
