Abstract: According to the analysis of the starting characteristic of induction motor and the comparison on PID control and fuzzy control, this paper presents a design method of induction motor soft starting based on fuzzy control. Through measuring input current, and processing fuzzy inference, the fuzzy controller can change the control angle of thyristor, keep the starting current constant and increase the terminal voltage, therefore get better control results. In terms of induction reality, this paper introduces the fuzzy control theory, the foundation of control model, the selection of control configuration and the realization of control decision.
