Vector Control of Permanent Magnet Synchronous Motor Based on Improved LADRC
In order to improve the response speed and anti-disturbance ability of vector control systems of permanent magnet synchronous motor(PMSM),an improved linear active disturbance rejection con-trol(LADRC)was proposed.An improved linear extended state observer(LESO)was designed based on the principle of error control.The stability of the improved LESO was verifide by the time domain analy-sis method.The anti-disturbance ability of the improved LESO was verified by the frequency domain analysis method.The simulation model was established based on MATLAB/Simulink,and the control ef-fects of improved LADRC and traditional LADRC were compared.The simulation results show that the improved LADRC has a faster response speed and stronger anti-disturbance ability.
