Detailed description of the invention
The present invention provides a kind of PG motor runing adjustment method and regulation system.For making the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, a kind of PG motor runing adjustment method being embodied as the present invention.The rotating speed that described PG motor refers to motor is controlled by the silicon controlled angle of flow rather than is controlled by relay.In motor runing adjustment, it is to use periodic adjustment strategy, that is the difference between predetermined refresh time, rotating speed and the rotating speed of target of detection PG motor, thus be adjusted.Thus, regulation process is made up of a series of adjustment actions repeated, and is described below as a example by an adjustment cycle.
Described method comprises the steps:
The rotating speed of target Tspeed that S100, the current rotating speed Cspeed gathering PG motor and acquisition are preset.
S200, the first difference DELTA S calculated between described current rotating speed Cspeed and rotating speed of target Tspeed, which represent the trend of change.That is, the first difference DELTA S=current rotating speed Cspeed-rotating speed of target Tspeed.
S300, according to described first difference and the operation trend of PG motor, determine regulation parameter M in the current adjustment cycle.
After the operation trend of described PG motor refers to the last adjustment of distance, the variation tendency of the difference between current PG motor speed and rotating speed of target.Difference between the two is to accelerate the states such as expansion/reduction that expand/reduce or slow down.It can include deviateing rotating speed of target and two kinds of operation trends of approaching rotating speed of target.Described operation trend is to calculate obtain according to the upper one regulation parameter adjusting the cycle and the current regulation parameter adjusting the cycle, it is judged that belong to any operation trend.Concrete, when upper one adjusts first difference in cycle less than or equal to current the first difference adjusting the cycle, it is judged that the operation trend of (thinking) described PG motor is deviation rotating speed of target；When upper one adjusts first difference in cycle more than current the first difference adjusting the cycle, it is judged that the operation trend of (thinking) described PG motor is approaching rotating speed of target.
Above-mentioned regulative mode is the self study based on the above one adjustment parameter adjusting the cycle, adaptive process.It predicts rotation speed change in advance according to rotation speed change trend and adjustment state, it is adjusted in advance, have employed readjustment and on the basis of original regulated quantity, be amplified the control method reduced, rather than being adjusted by rotating speed difference attachment coefficient simply, it is to avoid rotating speed accumulative overshoot condition of regulated quantity in change procedure.
S400, perform and store the regulation parameter in the current adjustment cycle.Adjust the cycle subsequently into the next one, repeat above-mentioned steps to realize the stable operation of PG motor.
Concrete, described regulation parameter may include that regulated quantity and regulation direction.Described regulation direction D includes improving rotating speed Up, reducing rotating speed Down and keep rotating speed Keep tri-kinds to regulate direction.Described regulated quantity refers to the degree of regulation, for scalar, does not has direction.
The above-mentioned setting that regulation direction and regulated quantity re-use the input parameter as regulated quantity, breaches the most simple restriction of the input parameter for regulating with rotating speed difference and adjustment factor, has good adaptability and versatility.
In a particular embodiment of the present invention, after step sloo, described method can also comprise the steps:
First, it is determined that whether current rotating speed is higher than rotating speed of target, when current rotating speed is higher than rotating speed of target, described first difference is forward, and when current rotating speed is less than rotating speed of target, described first difference is reverse；
Then, the upper one regulation direction adjusting the cycle is read.Further, read in the upper adjustment cycle, PG motor speed and the first difference Old Δ S of rotating speed of target.

Current offspeed rotating speed of target, and deviation speed quickening, strengthen regulated quantity time close to rotating speed of target.
Current offspeed rotating speed of target, deviation is relatively slow, from rotating speed of target farther out time strengthen regulated quantity.
Current offspeed rotating speed of target, and be that deviation strengthens regulated quantity suddenly.
Current offspeed rotating speed of target, and be that persistently deviation strengthens regulated quantity.
