异步电动机软起动的模糊控制器的仿真研究

Simulation Research of Soft-Starting Control System for Asynchronous Motor Based on Fuzzy Controller

针对异步电动机直接启动会产生很大电流的特性,提出了一种基于模糊控制原理的异步电动机软起动控制方法。利用MATLAB/SIMULINK对此控制系统建立了仿真模型并进行了仿真实验。仿真结果表明采用模糊控制的软起动方法可以有效地限制异步电动机的起动电流,因此该方法是正确有效的。

Considering the very large starting current brought by the asynchronous motors when being started, a soft-starting control method for asynchronous motors based on Fuzzy control theory was presented. The simulation model of the control system was built based on MATLAB/ SIMULINK and simulation was carried out. The simulation results expatiate that starting current of the asynchronous motor is limited in valid by using the soft-starting method based on Fuzzy control,so the method is correct and valid.
