Abstract：Non-smooth speed regulator based on time-varying parameter disturbance observer compensation for permanent magnet synchronous motor (PMSM) is proposed, aiming at eliminating the influence of external load disturbance and speed sampling signal distortions on the performance of speed control system. First, according to the analysis of the disturbances of the speed loop, the non-smooth control strategy is designed, so that the speed error of the closed-loop system can converge into a small region in finite time. Second, the time-varying parameter disturbance observer is introduced to estimate the total disturbance of the speed loop, and then the estimated value is used for feed-forward compensation. In order to achieve speed detection without time delay, the delay caused by the speed sampling filter is compensated in the observer. The simulation and experimental results verify the correctness and feasibility of the control strategy based on non-smooth control and time-varying parameter disturbance observer.
