Abstract:The non-ideal factors, such as the inherent chattering of sliding mode observer (SMO), the delay of control algorithm, and the dead-time effect, and so on, will produce harmonic errors of position estimation, which become the main factors affecting the accuracy of rotor position estimation. To improve the performance of the surface permanent magnet synchronous motor (SPMSM), a wideband synchronous fundamental-frequency extraction filter is proposed to extract the fundamental wave signal of the estimated back EMF. Then, a novel signal processing method combing wideband synchronous fundamental frequency extraction filter-frequency locked loop (WSFEF-FLL) is applied, and the application of FLL ensures the tracking frequency of the WSFEF adaptive. Using the WSFEF- FLL-PLL in the SMO based position estimator, the harmonics of the back EMF can be effectively eliminated, which improves the accuracy and dynamic performance of rotor position estimation. Simulation and experiment verify the feasibility and effectiveness of the proposed method.
