高性能模糊控制裹包机的感应电动机驱动系统的设计与实现

Design and Implementation of Induction Motor Drive System of a High Performance Fuzzy Control Binding Machine

针对接缝式裹包机的交流调速系统控制精度较差的问题 ,提出了具有模糊控制器的有限周期控制的感应电动机驱动。由于转矩和磁通是由有限周期控制技术调节 ,能达到极快转矩响应。将模糊控制器应用于速度控制反馈环节中 ,使该驱动系统具有高自适应能力 ,且对参数和工作条件改变是非常的不灵敏。

A limit-cycle induction controlled induction motor drive with a fuzzy controller was proposed to solve the problem of poor control precision in AC speed modulation. The torque and flux of the proposed drive system were regulated by the limit-cycle control technique that enabled the quick torque response. A fuzzy controller was used in the speed control feed back loop to obtain the feature of high adaptability. The performance of the controlled drive system is rather insensitive to the changing of parameter and operating condition.
