舰载机自动着舰模糊控制系统的设计

Design of Fuzzy Control Systems for Aircraft's Auto-landing on Carrier

采用解析形式的模糊控制规则，并提出了修正因子的模糊数模型。通过对量化、比例和积分因子寻优，并用二元函数的直线插值算法对修正因子的模糊数模型插值，可以克服常规模糊控制器所固有的模糊量化误差与调节死区，从而消除了由于量化误差而引起的系统稳态误差与可能发生的稳态颤振现象。使所设计的模糊控制系统具有在线自调整控制规则功能和良好的动、静态性能。

This paper adopts analytic control rules, and presents a fuzzy numbermodel of correction factor. By optimizing the quantified, propotional and integral factors, and interpolating the fuzzy numbers with binary function's linear interpolation method, the inherent fuzzy quantization errors and the regulation dead bands which exist in an ordinary fuzzy controller can be overcome, and the system's steady-state errors and flutters which may be caused by fuzzy quantization errors are eliminated essentially.The designed fuzzy control system can possess the function of self-regulating control rules on line, and good dynamic, static performance.
