基于扩展磁链模型的凸极永磁同步电机无传感器控制转子位置估计器

Starting from the classical dynamic model of salient-pole permanent-magnet synchronous machines (PMSMs) expressed in the stationary reference frame, this paper presents a mathematical model reconstruction process for salient-pole PMSMs, from which an extended flux-based machine model is derived. Compared with the commonly used extended electromotive force-based model, the extended flux-based model...
