摘要针对永磁同步电机转子初始位置检测已有方法存在的电机“抖动”、对电机参数依赖性强、高频电流信号数学处理算法复杂等问题,提出一种基于高频电压信号注入法的永磁同步电机转子初始位置检测方法。该方法通过对三相高频电压信号的电流响应进行低通滤波,比较三相电流响应幅值的大小关系,依据转子位置角θ对三相高频电流响应信号幅值的调制规律,得到电机转子初始位置信息,最后利用电机磁路饱和效应区分电机转子NS极性。理论分析及实验表明,该方法能准确检测出电机转子初始位置信息,电机转子不会发生“抖动”,检测方法对电机参数依赖性低,电流处理算法简单,不需要额外增加硬件电路,检测误差较小,可满足永磁同步电机的平稳起动要求。

Abstract：An estimation method for the initial rotor position for permanent magnet (PM) synchronous motor based on the high frequency voltage injection is presented on account of the problems in existing methods,which includes that the rotor may jitter,the methods depend highly on the motor parameters,and the mathematical processing algorithm of the high-frequency current responses during the estimation is complex.In the proposed method,the three phase high frequency voltage signals are laid on the motor first.By comparing the amplitudes of the three-phase high frequency current responses through LPF (low-pass filter),the method obtains the initial rotor position following the rules that the rotor position affects the amplitudes of the three-phase high frequency current responses.Then the motor magnetic saturation effect is used to distinguish the NS poles.The algorithms and the experimental results show that the proposed estimation method for the initial rotor position is correct.And during the estimation,the rotor does not jitter.The method does not need any additional circuits.The mathematical processing algorithm for the high-frequency current response is easy.And the estimation error is small.This estimation method can be used in motor’s smooth start.

Key words： Permanent magnet synchronous motor initial rotor position high frequency signal injection magnetic saturation effect
