Abstract: According to the characteristics of the ac motor starting process, design a fuzzy soft start controller, realize constant current of ac motor soft start control. Using fuzzy soft start controller uses the two-dimensional structure, current deviation and deviation change rate as input, Mining Mamdani inference method of fuzzy reasoning. The controller output to the adjustment of the thyristor trigger Angle. The results simulated by using Fuzzy toolbox to design. The results show that the fuzzy soft start controllers reasonable structure, simple rules, and easy to implement, motor soft start control to good effect.


Keywords: Soft start, AC motor, fuzzy control, Simulation.
