Study of Space Vector Algorithm for Induction Motor Based on Fuzzy PID Switch Control

摘要

In many induction motor control systems,there are some shortcomings in the conventional PID and fuzzy control system alone,which result in poor dynamicstatic effects,weak track and large overshootso according to the basic principle of space vector control and error range of speed and current,FuzzyPID hybrid control by automatic switch is proposed to control the speed loop and current loop of induction motor with the help of workers' experience,and the automatic switch is finished by a computer program,Through the simulation on Matlab/Simulink,Experiment results show robustness and dynamic-static response performance of the system are obviously improved,and the method makes the system has stronger track,in addition,overshoot is greatly reduced,Summary,Fuzzy-PID hybrid control by automatic switch has some reference value.
