Aiming at the problems of poor stability and low system accuracy in the vector control of PMSLM, a vector control strategy for PMSLM based on model reference adaptive system is proposed. Improve the accuracy of speed and rotor position estimation by selecting the appropriate adaptive law, and introduce a sliding mode control strategy in the speed loop to optimize the vector control system. The simulation results show that this method can effectively reduce the overshoot and chattering, and improve the stability of the system.
