摘　　要：针对永磁同步电机伺服系统中存在的速度控制精度不高、抗负载扰动能力差等问题,提出改进型自抗扰控制策略。设计嵌合降阶扩张状态观测器,内环观测广义扰动,外环观测剩余扰动。设计模糊自抗扰速度控制器,基于MATLAB/Simulink建立模型。仿真结果表明:基于改进型自抗扰的控制策略能够有效的改善系统的控制性能,对速度、负载变化具有较强的鲁棒性。The servo system of a permanent magnet synchronous motor(PMSM)has poor speed control accuracy and poor anti-load disturbance capability.In order to address these problems,an improved ac‐tive disturbance rejection control(ADRC)strategy was proposed.Nested reduced-order extended state observers were designed.Specifically,the inner-loop reduced-order extended state observer observed the generalized disturbance,and the outer-loop reduced-order extended state observer observed the re‐sidual disturbance.The fuzzy active disturbance rejection speed controller was designed.The model was built based on MATLAB/Simulink platform.The results show that the modified active disturbance rejection control strategy can effectively improve the control performance of the system and is more ro‐bust to speed and load variations.
