无刷同步电机无传感器启动控制的转子位置估计误差改进方法

This article proposed a sensorless starting control method for the brushless synchronous machine with the indirectly injected high-frequency signal, where the high-frequency signals are injected into the stator windings of the main exciter instead of the main generator. The impact of the nonlinear links of the rotary rectifier and various filters on the rotor position estimation error during the a...
