摘　　要：在基于模型参考自适应(MARS)理论速度观测器基础上,运用滑模变结构控制理论设计了永磁同步电动机(PMSM)的控制系统。该方法由Popov的超稳定性和Lyapunov稳定性理论保证了系统稳定的鲁棒性,和优良的动、静态性能。使用滑模控制理论设计的系统,响应时间快,且可有效抑制负载变化带来的扰动。文章对所提出的控制策略进行了理论分析,并且通过Matlab/Simulink进行了仿真实验。仿真结果表明,该控制方法较好地实现了电机的转速跟踪,改善了系统的动、静态性能。A Control method based on the model reference adaptive （ MARS } theoretical construct of permanent magnet synchronous motor speed observer using sliding-mode control theory was designed. The method consists of Popov stability and Lyapunov stability theory to ensure stability of the system, dynamic and static characteristics of good performance. Using the sliding-mode control theory, the overall control system can effectively suppress the disturbance brought about by load changes, fast response time, thus enhancing the robustness of the system. This paper proposed a theoretical analysis of control strategies, and by Matlab / Simulink simulation experiment. Simulation results show that the control method can effectively realize the motor speed tracking, has good dynamic and static performance and robustness.
