this paper describes fuzzy intelligent control applied in induction motor soft-starter. The fuzzy control strategy is tuned to the start current. A smooth start of the motor is achieved by adjusting the start currents of the induction motor using fuzzy decision and current oscillation are eliminated effectively. The software and hardware based on AT89C52 sing-chip computer and the flow are introduced. The emulator show ： the system start-up smooth is achieved by decreasing the current surge.
