Abstract

The ultra-high aspect ratio multi-body full-wing layout unmanned aerial vehicle (UAV) has advantages in long-endurance flight and mission flexibility, and thus has development potential. The multi-body connection mode and special full-wing layout unit make the dynamic characteristics and control scheme of this type of combined unmanned aerial vehicle special. In this paper, firstly, the multi-body flight dynamics model is established. Then, practical fixed time sliding mode control methods with adaptive laws are designed for aerodynamic-driven morphing-attitude control, and a fixed time control method with fixed-time observer is designed for airspeed control. The stability is guaranteed based on the Lyapunov theory. Furthermore, the observer-based fixed-time height controller and vector field-based horizontal straight-line path following controller are given to obtain actual pitch and yaw angle tracking commands for mission flight. Finally, multiple sets of numerical simulations are performed to demonstrate the superiorities and effectiveness of the proposed aerodynamic-driven active maneuver morphing and flight control in the presence of disturbance and model uncertainty.

具有扰动和模型不确定性的多体全翼布局无人机气动驱动主动机动变形与飞行控制

超高展弦比多体全翼布局无人机具有长航时飞行和任务灵活性等优点，具有发展潜力。多体连接方式和特殊的全翼布局单元使该型组合无人机的动态特性和控制方案具有特殊性。本文首先建立了多体飞行动力学模型。然后，针对气动驱动的变形姿态控制设计了实用的带自适应律的定时滑模控制方法，针对空速控制设计了带定时观测器的定时控制方法。稳定性是基于李亚普诺夫理论来保证的。在此基础上，提出了基于观测器的定时高度控制器和基于矢量场的水平直线路径跟踪控制器，以获取任务飞行的俯仰和偏航角跟踪指令。最后，通过多组数值仿真验证了气动驱动主动机动变形与飞行控制在扰动和模型不确定性条件下的优越性和有效性。
