基于相位提升扩张状态观测器的永磁同步电机开关准谐振控制设计

Achieving robust and precise speed regulation in permanent magnet synchronous motor (PMSM) drive systems remains a significant challenge, particularly under disturbances comprising both periodic and aperiodic components. For aperiodic disturbances, disturbance observers are commonly employed; however, conventional designs often exhibit slow convergence and phase lag, limiting their effectiveness. ...
