摘要
设计了一种渠道自调整模糊控制器,它能根据水位偏差 e和水位偏差变化率ec 的实时变化,通过自调整因子对模糊控制规则进行在线自动调整. 建立了一单渠段实验渠道,并采用 Matlab软件仿真。结果表明,采用自调整模糊控制器,系统响应加快,在抗干扰能力和参数变化时的适应性方面都优于普通模糊控制器,且有更好的动态性能和稳态性能.
An adaptive fuzzy controller is designed for canal control. With the changes of water level errors and the change rates, the fuzzy controller rules are adjusted on line by self-regulating parameters. The control system is numerically tested on a 1-pool canal using Matlab. The simulation results show that comparing with the common fuzzy controller, the adaptive controller has better performance in response time and adaptability. The steady and dynamic qualities are also better.
