基于自适应带宽广义积分谐振扩张状态观测器的IPMSM全速域无传感器控制

In this article, an IPMSM unified full-speed domain sensorless control method based on generalized integral resonance extended state observer with adaptive bandwidth (GIRESO-AB) is proposed. First, GIRESO-AB is proposed to estimate the fundamental frequency back electromotive force (BEMF) and high-frequency (HF) BEMF. GIRESO-AB has two estimation loops, one is a fast interference estimation loop b...
