三级同步电机转子位置估计的正交信号同步解调方法

In this article, based on the analysis of the rotor position estimation error caused by the asynchronous demodulation method and the low-pass filter (LPF), a novel quadrature signals synchronous demodulation method without the LPF is proposed for the sensorless starting control of the three-stage synchronous machine (TSSM). The second harmonic voltage caused by the rotating rectifier is employed a...
