Abstract

In order to reduce the effects caused by load torque disturbances,the frequency characteristics of permanent magnet synchronous motor(PMSM) servo system speed response model under load torque disturbance are studied.Based on the relationship between the speed fluctuation caused by load torque disturbance and the parameters of speed PI regulator,a variable gain PI(VGPI) control method for PMSM based on load torque feedback compensation is proposed.According to the variation of the specific frequency component of speed,the variable PI controller gain can be real-time modified in this control strategy.Meantime,a load torque observer based on Kalman Filter is designed and implemented by FPGA,which guarantees that the variation of load torque can be observed and compensated in real time.The capacity of load torque disturbance rejection of PMSM system is improved.Experimental results are given to verify the validity of the control scheme.

Key words： Permanent magnet synchronous motor(PMSM) load torque disturbance variable gain PI (VGPI) load torque observer
