摘要：为提高表贴式永磁同步电机（SPMSM）的控制精度、动态响应速度以及可调速度范围。通过引入自抗扰控制技术，在两相静止坐标系下，提出一种可以将包含转子位置信息的耦合项直接估计出来的方法。利用自抗扰控制技术的强解耦能力直接解耦电机方程，故无需向转子坐标系进行坐标变换来实现解耦，此外通过电流自抗扰控制器（ADRC）中扩张状态观测器（ESO）可以直接得到转子电角速度和转子位置角，避免了传统控制方法中多次变换和积分带来的累积误差。其在转速ADRC中利用自抗扰控制技术的非线性控制方法，扩展了调速范围，提高了控制精度。

Abstract: To improve the control precision, dynamic response speed and adjustable speed range of the surfacemounted permanent magnet synchronous motor (SPMSM).In this paper, a method of directly estimating the coupling term with rotor position information was presented in two stationary coordinate systems by introducing the active disturbance rejection control technique.By using the strong decoupling ability of the active disturbance rejection control technology to directly decouple the motor equation, it is not necessary to coordinate the transformation to the rotor coordinate system for realizing decoupling, in addition, through the expansion state observer (ESO) in the current active disturbance rejection controller (ADRC), the rotor angular velocity and rotor position angle can be obtained directly, the cumulative error caused by multiple transformations and integrals in traditional control methods is avoided. In the speed ADRC, the nonlinear control method of the auto disturbance rejection control technique was used to extend the speed range and improve the control precision.
Key words: SPMSM; active disturbance rejection control; sensorless control; extend state observer; nonlinear system
