Abstract
Aiming at the shortcomings of current permanent magnet synchronous motor control, such as electromagnetic torque pulsation, flux pulsation, poor anti-interference performance and slow response speed. This paper introduces the control method of high frequency injection optimization sliding mode permanent magnet synchronous motor. Through the establishment of PMSM vector mathematical model. The design is based on high frequency injection and optimized sliding mode controller, MATLAB/Simulink was used for modeling and simulation analysis. It turned out that Compared with the traditional high frequency injection method and sliding mode controller, the vector control of permanent magnet synchronous motor based on high frequency injection and optimized synovial controller has stronger anti-interference, better reduction of chattering, which can improve the characteristics of the system more effectively and meet the needs of actual motor control.
