摘　　要：针对滑模控制(SMC)中的抖振问题,采用了基于指数趋近律的准滑动模态控制,并提出了用改进遗传算法优化趋近律参数,提高系统动态性能的思路.对由PMSM构成的交流伺服系统进行仿真试验,结果表明该方法有效.In regard to the chattering problem of sliding mode control （SMC）, this paper attempts to propose Quasi - SMC based on index approach. A proposal was put forward that parameters of approaching law were optimized and dynamic performance of the system was bettered by improving genetic algorithms. A simulation experiment of exchange servo system composed of PMSM was performed. The results indicate that the method is effective.
