板球系统的模糊控制

摘要：本文重点阐述了一种运用于板球系统中的离散模糊控制算法，建立了模糊控制模型，设计出模糊控制规则，进行了模糊推理和模糊判决．通过大量离线计算，建立了模糊控制查寻表，取得了较好的控制效果，能使小球在板上自由滚动而不飞出小板．并且对PID、PD、模糊控制方法进行了仿真研究，得出结论，模糊控制方法在板球系统中的控制效果要更好些，系统更容易达到稳定．

Fuzzy Control Method for Ball and Plate System
Lei Wen-long
Abstract：A distributed Fuzzy control method is applied to the contro1 system of Ball ＆ Plate.The fuzzy control model，fuzzy control rules，fuzzy inference and fuzzy adjudication are developed.Off-line calculation and fuzzy control inquiry table are carried out。and good
control effect is obtained；the ball can  roll on the plate freely without flying out the plate.Simulation study Of PID．PD and fuzzy control using the tools of Matlab is made．Results show that the effect of fuzzy control is better than that of PID or PD．Under the control of fuzzy controller the control system of Ball&Plate is easier to reach stable.
Key words：fuzzy intelligent control；fuzzy inference；fuzzy adjudication；Ball&Plate control system
