摘　　要：为了改善永磁同步电机调速系统的响应速度,提出了一种创新的滑模控制律。在此基础上,对滑模速度控制器进行了改进,并引入了滑模扰动观测器。这一观测器能够将观测到的扰动值直接反馈至速度控制器的输出端,以减少负载扰动对系统性能的负面影响,进而增强了滑模控制的鲁棒性。通过Matlab/Simulink仿真验证,结果表明:相对于传统的PI控制和传统SMC控制,本研究所提出的新型趋近律在电机起动和负载突变情况下能够显著提升转速控制系统的稳定性和动态响应性。In order to improve the response speed of permanent magnet synchronous motor governing system,an innovative approach law sliding mode control law was proposed.On this basis,the sliding mode velocity controller was improved and the sliding mode disturbance observer was introduced.The observer can directly feed the observed disturbance value to the output of the speed controller to reduce the negative impact of the load disturbance on the system performance and enhance the robustness of the sliding mode control.Through Matlab/Simulink simulation,the results show that compared with the traditional PI control and the traditional SMC control,the new approach law proposed in this study can significantly improve the stability and dynamic response of the speed control system under the condition of motor start-up and load sudden change.
