摘　　要：为了提高永磁同步电机(permanent magnet synchronous motor,PMSM)调速系统的动态品质,提出了一种基于趋近律方法的滑模速度控制策略。为了解决传统指数趋近律所存在的缺点,文中首先设计了一种改进的指数趋近律算法,该方法能够根据系统状态距离平衡点的远近而自适应调整趋近律速度;基于改进的指数趋近率设计了适用PMSM调速系统的速度滑模控制器。通过仿真结果验证了所提控制算法的有效性和可行性。To improve the control performance, a siding mode speed controller strategy based on reaching law method is proposed for permanent magnet synchronous motor （PMSM） in this paper First of all, a novel reaching law method is designed to solve the existing problems in traditional reaching law, a novel siding mode control （SMC） based on the proposed reaching law method is designed by using of the advantages, which can effectively improve system robustness and response. All results show that the algorithm has the advantages of faster response, less stabilization error, and also the vibration is restrained effectively.
