Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, in a first embodiment of a motor operation control method of the present invention, the process includes: s1, acquiring the corresponding average rotating speed of the motor when the motor runs for at least one week in the process that the motor runs at the preset rotating speed; that is, before the motor works, the rotation speed of the motor is preset, that is, the motor is set to start to operate at the preset rotation speed, but actually, the motor is affected by factors such as load during operation, and the actual rotation speed may not be equal to the preset rotation speed. In the rotating work of the motor, the actual rotating speed of the motor needs to be acquired, and because the actual rotating speed of the motor has a certain relation with the running time of the motor, in order to ensure the accuracy of acquiring the actual rotating speed, the average rotating speed corresponding to at least one rotation of the motor is acquired.
S2, acquiring the instantaneous rotating speed corresponding to any commutation period of the motor in at least one week; that is, while the average rotation speed is obtained during the period of at least one week of the motor operation, the average rotation speed can be obtained at the same time, and the instantaneous rotation speed corresponding to any commutation period in the motor operation process can be obtained at the same time. The method comprises the steps of obtaining time corresponding to single commutation according to a position sensing device of the motor to obtain single-step running time of the motor, and calculating corresponding instantaneous rotating speed according to the single-step running time.
S3, establishing an initial PI control loop, and respectively acquiring a first proportional coefficient and a first integral coefficient corresponding to the average rotating speed and a second proportional coefficient and a second integral coefficient corresponding to the instantaneous rotating speed for the initial PI control loop; specifically, an initial PI control loop is established according to a motor system, and the motor can stably run by using an incremental PI and debugging KP and KI values through the speed difference of a preset rotating speed and an average rotating speed Back _ Spd _ Aver. At the moment, the KP and KI values are the first comparison coefficient KP1 and the first integral coefficient KI1 corresponding to the average rotating speed obtained by the initial PI control loop; the specific incremental PI formula can be as follows: err _ Ref _ value-Back _ value; Err-PreErr; Δ Out _ value ═ Err KI + DeErr KP; when PreErr is Err; then Out _ Value ═ Δ Out _ Value is finally obtained. On the basis of obtaining the first PI control loop, a second PI control loop is added, incremental PI is used for debugging KP and KI values through the speed difference of preset rotating speed and instantaneous rotating speed Back _ Spd _ Inst, so that the motor is enabled to be good in dynamic running condition on the basis of keeping static stable running, and the KP and KI values at the moment are a second comparison coefficient KP2 and a second integral coefficient KI2 corresponding to the average rotating speed obtained through the initial PI control loop.

The specific process includes obtaining the sum of the average reference current increment value Delt _ I _ Ref _ Aver corresponding to the first adjustment amount and the instantaneous reference current increment value Delt _ I _ Ref _ Inst corresponding to the second adjustment amount as the third adjustment amount Delt _ I _ Ref _ Aver + Delt _ I _ Ref _ Inst. Based on the incremental PI, the output quantity reference current I _ Ref + (Delt _ I _ Ref _ Aver + Delt _ I _ Ref _ Inst); namely, current chopping control is carried out on the motor according to the output quantity reference current I _ Ref obtained by the third adjustment quantity (Delt _ I _ Ref _ Aver + Delt _ I _ Ref _ Inst).
