用于表贴式永磁同步电机无传感器控制的渐近稳定降阶自适应观测器

The design of the back electromotive force (EMF) observer is important in sensorless speed control of surface-mounted permanent magnet synchronous motors. However, many existing back EMF observers are coupled with the phase-locked loop (PLL), which not only complicates observer design but also poses challenges in ensuring global asymptotic stability. To address this challenge, this article introdu...
