Abstract
The control accuracy of traditional deadbeat predictive control of surface-mount permanent magnet synchronous motors (SPMSM) is susceptible to model parameters and environmental disturbances. This paper introduces an internal model disturbance observer (IMDO) into the current loop predictive control, which can real-time compensation of d and q axis voltages to improve current loop control accuracy. First, according to the control model of SPMSM, calculate the stability domain of the predictive control algorithm; then, the observer is designed, and the system disturbance obtained by the internal model control equation is multiplied by the compensation coefficient to the d and q axis voltages. Finally, the simulation results verify that the proposed algorithm can improve the robustness of predictive control and improve the control performance of predictive control when the parameters are disturbed.
