  • 摘要:

    针对变体飞行器变形过程的控制问题,将切换系统理论与多变量自适应控制理论相结合,提出了一种基于切换系统的鲁棒自适应控制器设计方法。首先,建立了变体飞行器纵向短周期线性切换模型,描述了飞行器的整个变形过程;然后,设计了一种改进的鲁棒自适应控制律,抑制了各类干扰和不确定性对系统的影响,实现了切换系统对参考模型的良好跟踪;最后,提出了一种基于模型依赖驻留时间(MDDT)的切换控制律,保证了变体飞行器在变形切换过程中的稳定性,利用Lyapunov函数方法证明了本文方法最终一致有界。仿真验证表明,在存在外部干扰和各类不确定性的情况下,本文方法能保证飞行器在变形过程中精确跟踪参考模型,且具有较好的抗干扰能力。
