This article presents a novel finite position set-phase locked loop (FPS-PLL) to extract the rotor position of the permanent-magnet synchronous motors (PMSMs) using a sliding-mode observer. In order to achieve faster convergence speed and less iteration times, Newton iteration method is applied in r...
