| Abstract: | 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. |
