Super-twisting sliding mode control of permanent magnet synchronous motor based on voltage compensation. (August 2020) - Jinli, Xu
Abstract: In this paper, a compensation method for the expected voltage value was proposed to the problem of speed overshoot in traditional Super-twisting sliding mode control applied to permanent magnet synchronous motors (PMSM). This method combines the voltage change caused by the load angle change, overcomes the overshoot situation when the speed changes rapidly, and speeds up the time to reach the given speed. The proposed control theory is verified by MATLAB/Simulink software. Simulation results show that the proposed compensation method can successfully suppress speed overshoot and improve the dynamic response of speed.
