全速域内永磁同步电机

This article proposes a seamless sensorless control method for interior permanent magnet synchronous motor (IPMSM) drives across the full speed range. The method employs two generalized integral extended state observers to separately estimate the high-frequency (HF) and fundamental electromotive force (EMF) components under the IPMSM active flux model with $d$-axis HF voltage injection. Two identi...
