摘　　要：为了满足永磁同步电机高性能的控制要求,本文分析了变指数趋近律,针对永磁同步电机设计了一种基于变指数趋近律的滑模变结构控制器,并分析证明了该控制器的稳定性,然后通过仿真试验验证该方法的可行性和有效性。仿真结果表明:该方法克服了传统PI控制存在响应时间长、鲁棒性不强的不足,削弱了传统滑模变结构控制存在的严重抖振。To satisfied with the high-power control demand of the PMSM control drive system,this paper analyzed the priciple of variable exponent reaching law and devised a novel variable exponent reaching law of sliding control strategy,and then analyzed and proved the stability of the controller.At last,the feasibility and validity of this control strategy was verified by imitation and conducting experiment.The simulational and experimental results express：the strategy solved the problems that the time of response is too long and robustness of the system is unstrong.At the same time which weakens the serious chatting existed commonly in traditional sliding mode control.
