基于自抗扰控制器的交流直线永磁同步伺服电机速度控制系统

Speed Control System of AC Linear Permanent Magnet Synchronous Servo Motor Based on Auto-disturbance Rejection Controller

根据三相交流直线永磁同步伺服电机的非线性动态模型,采用自抗扰控制器的方法,对系统的内部扰动和外部扰动进行观测,并加以补偿。仿真结果表明,采用自抗扰控制器具有较好的动态性能以及对负载扰动、电动机参数变化都具有较好的鲁棒性。

According to the nonlinear dynamic mathematical model of the three-phase AC linear permanent magnet synchronous servo motor（AC-LPMSM）, the inner disturbance and outside disturbance can be observed with the auto-disturbance rejection controller（ADRC）, and use it to offset the system. The results of simulation test indicate that the ADRC has good dynamic performance and the strong robustness to both load disturbance and the parametric variation of motor.
