摘　　要：提出了一种基于高频电压信号注入法的永磁同步电机(PermanentMagnetSynchronousMachine,简称PMSM)无位置传感器控制方法,该方法适用于凸极永磁同步电机低速和零速时的位置检测。详细介绍了高频电压信号注入法的转子位置自检测原理,并采用!-"-#滤波方法得到转子位置和速度估计信息,建立了PMSM无传感器矢量控制系统的仿真模型,给出了实验结果。This paper presents a sensorless control method of salient-pole Permanent Magnet Synchronous Machine （PMSM） based on injecting high frequency voltage signal.The proposed method is feasible for position and speed estimation of salient-pole PMSM at a low speed,including zero speed.The basic principle of rotor position self-sensing using high frequency voltage signal injection is presented,and the position and speed estimations are achieved by using α-β-γ algorithm.The simulation model for PMSM sensorless vector control system is established by using the proposed rotor position and speed estimation.The experimental results are given.
