摘　　要：传统的PI调节器由于控制方法简单,被广泛应用于PMSM调速系统,但它往往不能满足高性能控制要求。通过将滑模变结构控制(SMC)应用于PMSM调速系统,针对一般滑模控制中控制量的求取需整定多个参数范围带来的复杂性问题,结合趋近律法设计了一种变参数SMC方法,给出了控制器的设计方法,并对所设计的系统进行了仿真分析和实验研究。结果表明该控制器使系统具有快速性、稳定性、无超调以及抗负载扰动强等优点,提高了系统的鲁棒性。Traditional PI controller is widely used in the speed can＇t meet the need of high performance. This paper proposed control of PMSM for its simplicity, but it a variable sliding model Control for PMSM We did simulation and experiment research on the speed control system respectively. The results demonstrated that the system had the advantages of fastness rapid response, stability, no over-shoot, rejecting load disturbance and etc, improved the robustness of the system.
