[Abstract]:According to the model of permanent magnet synchronous motor (PMSM), it is predicted that the speed regulation system controlled by PMSM will be unstable in operation, and its speed fluctuates greatly when it is disturbed by external disturbance. A model predictive current control method for PMSM based on discrete sliding mode control with load disturbance observation is proposed. Based on the research of model predictive current control algorithm for surface permanent magnet synchronous motor, a discrete sliding mode speed controller is designed to replace the proportional differential PI controller, which can restrain overshoot and improve the system startup performance. A discrete sliding mode disturbance observer is proposed and feedforward compensation for the load is proposed, which effectively restrains the external disturbance and improves the robustness of the system. The simulation results show that the control strategy can improve the dynamic performance and steady-state precision of the system.
