Abstract
In order to solve the problems of slow speed error convergence speed and serious jitter in the traditional sliding mode control of permanent magnet synchronous motor,this paper proposes a terminal sliding mode control of PMSM based on extended high-order sliding mode disturbance observer.Firstly,an adaptive reaching law and an integrated terminal sliding mode are designed,which combine the two to design an adaptive integrated terminal sliding mode velocity controller to improve the global convergence speed of the systematic error and weaken the jitter.Secondly,in order to improve the observation accuracy and dynamic response speed of the observer,an extended high-order sliding mode disturbance observer is designed to realize the external disturbance compensation of the controller.Finally,through the comparison of simulation results,it is confirmed that the proposed method can effectively suppress the system jitter and improve the system error convergence speed and robustness.关键词
