展向变形飞行器机翼扭转时的鲁棒飞行控制与分析

为了研究机翼扭转变形对飞行器纵向飞行性能的影响,本文采用小扰动线性化方法建立展向扭转变形飞行器的变参数模型,运用鲁棒最优方法设计机翼扭转变形时的纵向飞行控制律,并用S函数编写展向变形飞行器模型,最后采用SIMULINK对设计的控制律进行仿真分析。仿真结果显示,设计的鲁棒最优控制律能够对变形飞行器进行飞行控制,并且机翼完全扭转能够辅助飞行器下降,机翼不完全扭转能够辅助飞行器爬升。

Robust flight control and analysis of aircraft with spanwise morphing

To research influence of torsional deformation of wing on aircraft longitudinal flight performance. This paper adopts small disturbance linearization method to establish the parametric models of the torsional deformation. Robust optimal control method is used to design torsional deformation of longitudinal flight control law. S-Function is used to write the model of aircraft with spanwise morphing. Finally, SIMULINK is used to analysis the designed control law. Simulation results show that design of robust optimal control law can be used to the morphing aircraft flight control. And full wing torsion aided aircraft to drop, part wing torsion aided aircraft to climb.
