Abstract：In view of the problem that the phase lag of the filter affects the dynamic performance of the system in the pulsating high frequency signal injection method, this paper starts from the controller point of view, and introduces the model predictive control (MPC) into the velocity loop instead of proportional integral (PI) control, using its rolling optimization and feedback correction characteristics to improve the dynamic performance of the system. At the same time, the commonly used MPC is improved to obtain better control performance. In order to obtain better anti-load disturbance capability, the load torque compensation strategy is adopted to analyze the existing problems of the traditional q-axis reference current feedforward compensation under MPC, and a new compensation method based on the q-axis reference voltage is proposed to obtain better compensation effect.
