中文摘要：

以伸缩翼变体飞行器为对象，研究了机翼伸缩辅助机动飞行的建模与控制问题。建立了飞行器气动参数与翼展变形率的函数关系，将机翼伸缩视为辅助操纵方式，构建了变形辅助机动的动力学模型。针对飞行器模型高度非线性的特点和机翼伸缩等会引起复合干扰的问题，提出了一种基于反馈线性化的非奇异动态终端滑模控制（non-singular dynamic terminal sliding mode control，NDTSMC）策略，在保证有限时间收敛的基础上，通过对切换信号的积分作用消除抖振，实现对不确定性的抑制。仿真结果表明，非奇异动态终端滑模控制方法能提高变体飞行器的控制精度和鲁棒性能，更好地消除抖振；变形辅助机动的变体飞行器比常规飞行器具有更强的机动性能和抗干扰能力。

英文摘要：

The modeling and control of the telescopic morphing aircraft for morphing-aided maneuver are studied in this paper.The relationships between the aircraft wingspan-varying and the aerodynamic parameters are analyzed.Taking the wingspan-varying as an extra operation,the dynamic model of the morphing-aided ma-neuver is constructed.To deal with the high nonlinearity and the hybrid disturbances,a novel feedback linear-ization based non-singular dynamic terminal sliding mode control （NDTSMC）approach is proposed.The con-vergence of the aircraft states within a finite time is guaranteed by the NDTSMC,and the chattering is elimina-ted by integration of the switch control signals.The simulation results show that the control precision and the robustness of the morphing aircraft are improved by the NDTSMC with a better chattering elimination.The ma-neuverability and the disturbance rejection capacity of the morphing aircraft with morphing-aided maneuver are demonstrated stronger than the conventional ones.
