基于变比例因子的三相异步电动机的模糊控制器

The fuzzy logical controller of a three-phase induction motor with variable scale factors

针对异步电动机传统起动方法的不足,本着增大起动转矩、减小起动电流的目的,通过对模糊控制器进行分层次结构设计,在加入变比例因子控制以后,通过不断地调整比例因子,使电动机达到最佳输出状态,改善了系统的动态性能。实验表明,这种控制与PID控制相比,其综合性能指标较佳,且系统建模简单,因此发展潜力很大。

The design method of fuzzy logical controller of an induction motor is presented. The starting torque of the motor is increased, and the starting current is decreased. Through adjusting the variable scale factor, the best performance of the induction motor is obtained. Experiment shows that this kind of control is better than the PID control, and the system model is much simple.
