摘要

提出了一种无速度传感器异步电动机转子磁链角跟踪的控制器结构。该方法是在基波感应电机模型的基础上，增加了机械动力学。将低频电流测试信号注入定子绕组，利用定子电压的响应产生误差信号，通过迫使电流信号进入转子磁链的方向，可以将误差信号控制为零。仿真和实验结果验证了该方法在定子频率和转速均为零的情况下的有效性。

Rotor flux angle tracking controller for sensorless induction motor drives

A controller structure is proposed for the tracking of the rotor flux angle in a speed sensorless induction motor. The method is based on the fundamental-wave induction motor model that is augmented with the mechanical dynamics. A low-frequency current test signal is injected into the stator winding, and the response of the stator voltage is used to produce an error signal that can be controlled to zero by forcing the current signal into the direction of the rotor flux. The validity of the method down to zero stator frequency and speed is confirmed by the results of simulations and experiments.
