非线性自航器弹道模糊控制系统设计

DESIGN OF A FUZZY CONTROL SYSTEM FOR NONLINEAR VEHICLE USING ON-LINE SELF-REGULATING FUZZY CONTROL RULES

提出了一种在线插值的规则自调整模糊控制新方法 ,它能从本质上消除量化误差和调节死区给模糊控制系统带来的稳态误差和颤振现象。用其为某非线性自航器设计了弹道控制系统 ,并进行了仿真研究 ,仿真结果表明 ,该弹道模糊控制系统不仅具有较好的动、静态特性 。

A new method of control applying self regulating fuzzy control rules with on line interpolation is presented. Shortcomings of conventional fuzzy control system viz. steady error and flutter phenomenon can be overcome using this method. Based on it a trajectory fuzzy control system is designed for an underwater vehicle with high nonlinearity. Simulation results show that the designed vehicle trajectory fuzzy control system possesses not only better dynamic and static properties, but also strong adaptability to changes in initial conditions and system parameters.
