摘要
为了提高感应电动机直接矢量控制系统对参数变化和负载扰动的鲁棒性 ,提出并设计了两种模糊逻辑控制器分别对系统的速度和磁链进行控制 ,速度和磁链控制器的结构均为模糊PI型 ,优化模糊控制器的隶属函数分布以增强其控制性能 .
In order to improve the controlled system robustness under parameter variations and load disturbance, two fuzzy logic controllers were presented to control speed and flux for induction motor direct vector control drive. The structures of the speed and flux controllers were fuzzy PI type. The membership function distributions of fuzzy controllers were optimized to enhance the control performance. The simulation results show that these controllers obviously improved the dynamic and static performance of the controlled system.
