一种基于SOGI的交叉耦合滤波方法，用于低成本PMSM驱动中的速度与位置估计

The extraction of high-resolution rotor position and speed from the Hall signals of permanent magnet synchronous motors (PMSMs) can be achieved through a filtering process based on second-order generalized integrators (SOGIs) and a phase-locked loop (PLL). This article proposes a novel SOGI-based cross-coupled PLL (CCSOGI-PLL) method that incorporates a notch coefficient, $d$, to enable arbitrary ...
