摘　　要：基于模糊逻辑控制策略,提出了一种新型的感应电机速度控制方法.设计出了一个模糊逻辑控制器用于外环控制.在不同的动态运行情况下,如给定速度突变、负载的阶跃变化等,分别采用新型模糊逻辑控制器和传统比例积分控制器对感应电机驱动性能进行仿真.对比实验结果表明:所设计的模糊逻辑控制器具有更强的鲁棒性,说明在高性能驱动的工业应用场合所提出的模糊逻辑控制器完全可以取代传统的PI控制器.A novel speed control scheme of an induction motor （IM） using fuzzy logic control is proposed. The fuzzy-logic controller （ FC）, which is based on the indirect vector control, is employed in the outer loop. The complete vector control scheme of the IM drive incorporating the FC is experimentally tested. The performances of the proposed FC based IM are investigated and compared with those obtained from the traditional proportional integral （PI） controller at different dynamic operating conditions such as sudden change in command speed, step change in load, etc. The results show that the FC is more robust and hence found to be a suitable replacement of the conventional PI controller for the high performance industrial drive applications.
