摘　　要：基于转子凸极追踪的思想,在永磁同步电机定子绕组注入高频电压,对提取的电流进行坐标变换,获得转子位置信息。将该信息送入特别设计的转子位置估测器中,可以得到转子的精确位置。设计转子位置估测器的结构和算法,对其进行仿真研究,仿真结果证明了该方法的正确性。Based on the rotor saliency-pole tracking idea, rotor position can be obtained when a high-frequency voltage signal was injected into stator winding and a coordinate transformation was made against the stator current, Input the current that contained rotor position information into a rotor-position-estimator, then the rotor position would get accurately, Formulate the structure of the estimator and its algorithm, The simulation results verified the method.
