基于直接速度估计与虚拟Z脉冲过零校正的SPMSM与IPMSM无传感器控制

This article proposes a direct speed estimator based on the sliding mode principle (SM-DSE). Unlike conventional methods that rely on intermediary signals such as back electromotive force and high-frequency response current to obtain speed and position information, the SM-DSE achieves full-speed range noise-free sensorless control without any intermediary signals. It is also applicable to both sur...
