Speed control of Permanent Magnet Synchronous Motor system using quick-power reaching law based on sliding mode control

Permanent magnet synchronous motor is a nonlinear, strongly coupled, and multivariable complex system. The traditional PI controller has poor dynamic performance and weak anti-interference ability. It cannot accurately adjust the system speed. To improve the anti-interference ability and dynamic response performance of the permanent magnet synchronous motor speed regulating system. In this paper, quick-power reaching law (QPRL) is applied to the sliding mode controller, and the design process of current sliding mode controller and velocity sliding film controller is described in detail. Finally, the permanent magnet synchronous motor sliding mode control speed regulation system is simulated by MATLAB/Simulink, and compared with the simulation results of the traditional exponential reaching law controller and traditional PI controller.
