Abstract In this paper the speed regulator based on sliding mode control strategies is used in the vector control of permanent magnet synchronous motor (PMSM) system. An integral and exponential time-varying sliding mode controller is proposed, which can avoid the problems of weak robustness and poor performance of dynamic response. The integral of speed error is introduced into sliding surface to avoid the requirements of the acceleration signal and enhance the system’s anti-jamming capability. Then the time-varying term is introduced to improve the convergence speed of the sliding surface in the context of ensuring global stability of the system. Experimental results obtained from PMSM control system experimental platform show that the integral time-varying sliding mode control achieves a precise speed control. Compared with PID traditional methods, the proposed sliding mode controller has better and faster tracking performance.

Key words： PMSM vector control speed control time-varying sliding mode
