| 摘 要： | 以通用高超声速飞行器GHV为研究对象,针对其俯仰通道设计了具有良好鲁棒性的飞行控制系统.为了便于应用滑模控制理论,对该模型进行了输入输出反馈线性化,将其转换成仿射型.鉴于鲁棒性与抖振的矛盾,基于指数趋近律完成了滑模控制律结构设计,进而采用了模糊控制理论改进指数趋近律.基于遗传算法完成了所有控制参数的设计,确定了模糊逻辑...

| Abstract: | According to the six DOF nonlinear model of the pitching channel of the generic hypersonic vehicle GHV,two sliding mode control laws are presented,which are based on the index reaching law and the fuzzy reaching law respectively.By taking advantage of the sliding mode control theory,the six DOF model is transformed into an affine system through input-output feedback linearization.To make the compromise between robustness and chattering,the structure of sliding mode control law based on the index reaching la... |
