基于超螺旋滑模观测器的永磁同步电机无传感复合控制
Sensorless Composite Control of Permanent Magnet Synchronous Motor Based on Super-twisting Sliding Model Observer
摘要
Abstract
To address the issues of low rotor estimation accuracy and slow dynamic response in the sin-gle sensorless control strategy for permanent magnet synchronous motors(PMSM)across the full speed range,a sensorless composite control strategy combining current frequency ratio control(IF)and a lin-early adaptive super-twisting sliding mode observer(LSTA-SMO)was proposed.At low speeds,IF con-trol was adopted.For medium and high speeds,the LSTA-SMO was introduced to mitigate the high-fre-quency chattering of the traditional super-twisting sliding mode observer.The rotor position information was then extracted using a phase-locked loop.To ensure a smooth transition between the two strategies,a weighted average approach was employed,which enhanced the stability of the system control across the full speed range.the simulation results in the MATLAB/Simulink environment demonstrate that,the proposed composite control strategy improves speed estimation accuracy by approximately 51.5%com-pared to the single control strategy,further validating the effectiveness of the proposed approach.关键词
