In order to improve the control effect of the traditional AC asynchronous motor vector control system and solve the problems of slow response speed and steady-state jitter caused by the characteristics of AC motor,a fuzzy adaptive vector control system was designed,the traditional vector control system was improved,a four-loop vector control system oriented by the rotor magnetic field was designed,and a fixed value controller was added for the steady-state fluctuation problem of traditional vector control.A simulation system was built in MATLAB/Simulink,and the rectifier inverter circuit used in AC asynchronous motor was designed to make the experimental results more realistic.The simulation results show that the dynamic performance of the designed four-loop control system is better,faster response,improved load resistance,and has stronger adaptability and robustness.
