摘　　要：针对永磁同步电动机转子初始位置检测问题,利用估计坐标系下输入高频电压,永磁同步电动机响应电流包含转子位置信息的特性,提出了一种检测方法。并使用MATLAB/Simulink工具箱来建立仿真模型,对所提出方法的正确性及性能进行验证。仿真实验表明:所提出方法可以快速、准确地检测出永磁同步电动机转子初始位置,并且方法简单无需设计滤波器,所需计算量很少,检测过程时间不受转子位置等因素影响,符合工程应用要求。To solve the initial rotor position detection problem of PMSM, a detection strategy was described, basing the characteristic that the rotor position information is contained in the current during injecting high frequency voltage signal in the estimation coordinate. The simulation model was built using MATLAB/Simulink toolbox, and experiments were carried on to verify the correctness and performance of the proposed strategy. The experiment results demonstrate that the rotor position could be detected rapidly and accurately using the proposed strategy, besides it is simple, needs no filter design and less computation, the detection process is not affected by the factors like rotor position, so it is suited for engineering application.
