摘要：在使用优化的自抗扰控制（ADRC）代替传统比例积分（PI）控制的基础上，分别建立基于模型参考自适应法和脉振高频注入法的位置辨识系统，以满足永磁同步电机（PMSM）不同速度范围内的辨识精度需求。所设计的自抗扰控制器中，保留非线性微分跟踪器（TD）的同时以线性误差控制律代替非线性状态反馈控制律（NLSEF），使模型得以简化。仿真结果表明：简化后的ADRC能在两种无位置传感器控制方法中取得较好的控制效果，和PI控制相比，系统抗扰动性更强，电机位置和速度辨识效果也更优。

Abstract: On the basis of using improved Active Disturbance Rejection Control（ADRC） to replace the traditional PI regulation，The position identification system based on model reference adaptive system（MRAS） and pulsating highfrequency injection method has been established.The control system can meet the needs of identification accuracy in different speed rangefor Permanent Magnet Synchronous Motor（PMSM）. In the active disturbance rejection controller（ADRC），reservation Tracking Differentiator（TD）and the linear error control law was used to instead of the Nonlinear State Error Feedback（NLSEF）control low which simplifies the model. The simulation results show that the improved ADRC can achieve better control effect in the two sensorless control systems. Compared with PI control, the system has better performance in robustness， motor position and speed identification.
