基于模糊逻辑的高速飞行器一体化控制律

An Integrated Control Law for Hypersonic Vehicles Based on Fuzzy Logic

针对通用高超声速飞行器的非线性模型,提出了一种一体化控制器的设计方法。基于动态逆理论,把非线性模型转换为等价的仿射系统;为等价系统设计模糊逻辑控制器,并基于遗传算法优化模糊逻辑控制参数。仿真表明,该方法能提供满意的鲁棒性、平滑的指令和快速收敛的模糊规则。

An integrated control law is presented by considering a nonlinear model of generic hypersonic vehicle as a plant.Based on dynamic inverse theory,the nonlinear model is transformed into an equivalent affine system.Then a fuzzy logic controller can be designed for the equivalent system.And fuzzy logic control parameters are optimized,which are based on genetic algorithm.The simulation results show that the satisfied robustness,smooth commands and rapid convergence of the fuzzy rules can be supplied by above method.
