Augmented nonsmooth observer for sensorless permanent magnet synchronous motor drives with harmonic suppression

Qiankang Hou, Bin Ma, Shihong Ding, Bing Shi et autres

To enhance the performance of the permanent magnet synchronous motor (PMSM) sensorless drive, an augmented nonsmooth observer (ANSO) combined with the modified quadrature phase-locked loop (Q-PLL) is constructed in this article. Different from the extensively utilized sliding mode observer with discontinuous switching …
