一种基于高频信号注入的内埋式永磁同步电机无传感器控制统一解调方法

High-frequency signal injection method is a common control strategy for interior permanent magnet synchronous motor (IPMSM) drives at zero and low speeds. A reasonable demodulation method is the key to successfully extracting the rotor position information. In conventional demodulation methods, the demodulation processes generally need to consider the impact of time-delay effect on demodulation si...
