In order to solve the problems of large torque speed pulsation and waveform distortion in the traditional PI control method for weak magnetic control of PMSM of electric vehicles, a new weak magnetic control method for PMSM was proposed based on sliding mode control in this work. Firstly, the mathematical model of the motor is established, then the controller is designed according to the weak magnetic control theory and the principle of sliding mode control, and finally the simulation analysis is established by MATLAB/Simulink. The results of simulation evaluation turned out that compared with the traditional PI weak magnet control, the response speed, anti-interference ability and robustness of control system were improved when the proposed control method was used.
