本文介绍了一种基于脉动高频电压信号注入法实现面装式永磁同步电机无传感器控制的方法。利用面装式永磁同步电机的磁饱和效应，在和转子同速旋转的坐标系注入脉动高频电压信号，对提取的电流进行坐标变换和解调，获得转子位置信息，实现了无传感器控制策略。仿真结果证明了该方法的正确性。

Sensorless control of PMSM based on fluctuating high frequency voltage signal injection WangFei, Fan Qi-Fu (Institute of Automation, Shanghai Jiao Tong University, Shanghai 200240) Abstract: A method to implement sensorless control of Surface Mounted PMSM based on fluctuating high frequency voltage signal injection was introduced. With the magnetic saturation of Surface Mounted PMSM, rotor position could be obtained when a fluctuating high frequency voltage signal was injected at synchronous coordinate and a coordinate transformation and demodulation were made against the stator current. The simulation results verified the method.
