一种自适应同步滤波器和正交锁相环相结合的滑模观测器
A Sliding Mode Observer Based on Combination of Adaptive Synchronization Filter and Quadrature Phase Locked Loop
摘要
Abstract
In order to accelerate the speed and improve the position observation performance of surface-mounted permanent-magnet synchronous motor (SM-PMSM), a sliding mode observer (SMO) was proposed combined with adaptive synchronization filter (ASF) and quadrature phase lock loop (PLL). Firstly, based on the mathematical model of the motor, the sliding mode current observer was constructed and the back electromotive force (back-EMF) was obtained. Secondly, using the position signal calculated by the phase-locked loop as the reference, the filter adjusted the band-pass cut-off frequency adaptively, filtered out a large amount of buffeting and harmonics in the back electromotive force, and output the fundamental back-EMF synchronously. Then, the phase-locked loop calculated the rotor speed and position based on the fundamental back-EMF. Finally, a simulation model of Matlab/Simulink and a hardware-in-the-loop simulation platform based on dSPACE were built. Simulation and experimental results show that the proposed method has good tracking performance and robustness to motor parameter perturbation.关键词
