摘  要：通过仿真分析，传统的速度PI调节器和位置P调节器无法满足高性能永磁交流伺服系统中快速动态响应的要求。针对以上不足，在传统调节器的基础上，速度调节器和位置调节器分别引入了变结构与微分负反馈相结合的方法和变结构的方法。仿真和实验结果均证明了双变结构控制能够有效地优化系统的快速动态响应性能。

Abstract: According to the simulation analysis for PMSM AC servo system,traditional speed PI adjustor and position P adjustor can not satisfy the requirements of rapid dynamic response for PMSM AC servo system with high quality.Aiming at the shortage above,in the foundation of traditional adjustors,the variable structure and the differential negative feedback were introduced in the speed adjustor,and the variable structure was introduced in the position adjustor.The simulations and experiments proved that the dual variable structure control could effectively improve the rapid dynamic response performance of system.
