摘要
在永磁同步电机的控制中往往使用矢量控制系统,其包括电流环、转速环和位置环等3种反馈调节。传统控制方案为PID控制,通过调节其参数改善控制效果。但当扰动存在且比较大时,PID的控制效果往往不佳。在系统中使用二阶自抗扰(Sencond-order Active Disturbance Rejection Controller,ADRC)控制器代替转速环反馈。永磁同步电机矢量控制系统的二阶ADRC控制器可以提高系统鲁棒性,仿真结果同样支持这一结论。
In the controlling of PMSM,vector control system was often used,which included three feedback regulation like current loop,speed loop and position loop.The traditional control scheme was PID control,which improved the control effect by adjusting its parameters.However,when the disturbance existed and was large,the control effect of PID was often unsatisfactory.In the system,the second-order active disturbance rejection controller(ADRC)was used instead of the speed loop feedback.The second order ADRC controller of PMSM vector control system can improve the system robustness.The simulation results also supported this result.
