Research on Intelligent Soft Starting Method for Three-Phase Asynchronous Motor Based on MATLAB

Abstract:

Considering the very large direct starting current of three-phase asynchronous motor, this paper presents a design method of asynchronous motor soft starter based on a intelligent control- fuzzy adaptive PID control. The simulation model of the soft starting control system is established with the power system blockset in MATLAB/SIMULINK software. The simulation results show that the fuzzy adaptive PID control method can effectively limit the motor starting current and it is better than the control effect of traditional PID control. Therefore, the fuzzy adaptive PID control scheme presented in this paper is correct and feasible.
