基于SPWM的改进滑模永磁同步电机自适应无感控制
Adaptive Sensorless Control of Improved Sliding Mode Permanent Magnet Synchronous Motor Based on SPWM
摘要
Abstract
An improved sliding mode adaptive sensorless control strategy based on SPWM was pro-posed to solve the problems of high chattering,low response velocity,and phase delay in traditional sliding mode controllers and sliding mode observers for permanent magnet synchronous motors(PMSMs).Firstly,the third harmonic was added to the SPWM voltage modulation method,which is rarely employed and easy to implement in engineering,to improve the DC voltage utilization.Secondly,a new gradual-change reach-ing law was designed to improve the velocity sliding mode controller.Finally,a new adaptive Super-Twist-ing sliding mode observer was designed to observe the rotor angle and velocity.Comparison between the proposed strategy,the traditional velocity PI&sliding mode observer,and the traditional velocity sliding mode&sliding mode observer strategies through simulation shows that the velocity chattering amplitude of the proposed strategy is decreased by 60.71%and 16.98%respectively,and the response time is shortened by 0.025 s and 0.004 s.Additionally,its sensorless strategy solves the phase delay problem caused by tradi-tional low-pass filters.关键词
