基于虚拟多相驱动的永磁同步电机谐波电流注入方法

This letter focuses on harmonic current regulation for permanent magnet synchronous machines (PMSMs) with distorted back electromotive forces (EMFs). The key is that an improved harmonic injection scheme is proposed based on a virtual nine-phase PMSM system to decompose harmonic currents without digital filters as in traditional approaches. This enables independent harmonic current regulation with...
