摘要
选择变形翼飞行器的巡航和俯冲两个飞行模态作为研究对象,给出变形翼飞行器的两个特定飞行模态对应的运动学数学模型。由于被控对象的非线性以及结构变化引起的参数不确定性,设计了自适应姿态控制律。基于Lyapunov稳定性定理证明了所提出控制方法的可行性,实现了对飞行器的姿态控制。并运用VC++编程语言结合OpenGL图形库,创建飞行器飞行环境;利用VC++/Simulink混合编程实现数据传递,较精确地实现了变形翼飞行器在两个不同模态间动态变化飞行过程,验证了所提出方法的有效性。
This work specifically studies a transformation of morphing aircraft from loitering to dashing.The nonlinear dynamic functions of the morphing aircraft in the different morphing process are derived.By considering the nonlinearity and uncertainties of parameter caused by the variable structurean adaptive attitude control law was designed for two flying models of morphing aircraft.The feasibility and effectiveness of this method were proved based on Lyapunov theory.The flight environment system for simulation was established based on VC＋＋ and OpenGL.And data from Simulink was successfully passed to the simulation system based on VC＋＋/Simulink program.The simulation results shows that the technologies proposed provide an effective way to simulate different flying procedure of morphing aircraft.
