基于新型等效模糊滑模观测器和改进软件锁相环的永磁同步电机矢量控制
Vector Control of Permanent Magnet Synchronous Motor Based on New Equivalent Fuzzy Synovial Control and Improved Software Phase Locked Loop
摘要
Abstract
In order to obtain the motor speed and rotor position accurately,a new control method based on the new equivalent fuzzy sliding mode variable structure and improved SPLL was proposed.Based on the traditional equivalent sliding mode variable structure,through changing the switching function,making the switcher fuzzication,reduced the output' s vibration of the observer,eliminating the low pass filter and the compensation of the rotor angle;Due to the motor's own excitation,magnetic circuit and other reasons,harmonics would be produced.And after the dq coordinate transformation and PI regulation,its output was no longer a frequency deviation.Therefore,it was necessary to use the improved SPLL to get the higher precision of the motor speed.The simulation structure showed that this method had the advantages of fast response,small overshoot,strong robustness to external load disturbance and parameter variation.关键词
