摘　　要：提出了一种永磁同步电机转子位置估算的自检测方法。文中讨论了利用旋转矢量载波高频信号注入、外差法及跟踪观测器检测转子位置的原理。同时给出了针对内埋式永磁同步电机的实验系统及实验结果。This paper presents an implementation of rotor position estimation with self sensing method for permanent magnet (PM) synchronous machines. The methods using rotating vector, carrier frequency excitation and heterodyning, tracking observers for rotor position estimation are discussed. The experimental system used for this work is presented. The experimental results for the case of a buried PM machine are shown in the paper.
