伸缩翼飞行器随着飞行任务变化而相应的改变其外形,始终保持最优飞行状态,以达到在复杂飞行环境中执行多种任务的要求。文中首先建立伸缩翼无人机运动模型和变形过程的气动模型,随后采用根轨迹方法设计PID控制器,实现对飞行器的纵向控制,最后采用仿真方法研究飞行器伸缩翼的变形过程,通过对比选择最佳伸缩变形时间。

Morphing aircraft changes its profile to fit the varied flight tasks, and the optimal states are kept to complete requirement of task under complex conditions. In this paper, firstly, the kinematic model and morphing aerodynamic model of morphing aircraft were built, then longitudinal control of aircraft can be realized by PID controller, at last, flexing wing process was researched by simulation, and the best morphing time can be selected.
