Summary: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 rotor position retrieval that just needs three iterations. The dichotomy of position combined with a novel cost function is adopted before the Newton iteration ensuring the astringency of iteration. Based on the above design, the calculation of the proposed FPS-PLL is significantly reduced. Additionally, the proposed method does not require complex parameter tuning compared with the conventional PLL. Simulation results proves the effectiveness of the proposed method.
