摘要

本文研究了一种可转换无人机(CUAV),其主要特点是在发射或回收时进行悬停飞行,在巡航时进行水平飞行。采用牛顿-欧拉法建立了考虑气动效应的动力学模型。提出了一种基于四元数的自适应反演控制方法。闭环系统保证了系统在无奇点表示下的稳定性。通过数值仿真验证了飞行器的性能和闭环系统的稳定性,最后对无人机的航电系统进行了描述。

Adaptive backstepping control for a convertible UAV
This paper focuses on a convertible unmanned aerial vehicle (CUAV) whose main characteristics is to perform hover flight for launch or recovery, and horizontal mode during cruise. The dynamic model is obtained using the Newton-Euler approach and it considers the aerodynamic effects. An adaptive backstepping control, based on quaternions, is proposed for the complete operation of the CUAV. The closed-loop system guarantees the stability under a singularity-free representation. Numerical simulations show the performance of the aerial vehicle and the stabilization of the closed-loop system, and finally the avionics of the CUAV is described.
