摘要:

本文提出了一种轨迹跟踪控制器,用于多旋翼无人机(UAV)在仅已知期望位置和航向而未知高阶导数的场景。所提出的解决方案改进了最先进的几何控制器,有效解决了期望姿态不存在相关的挑战,并确保所有时刻的总推力输入为正。我们通过引入新颖的非线性滤波器结构,解决了轨迹高阶导数不可用的额外挑战。我们从理论上形式化了这些滤波器结构对系统误差动态的影响。随后,通过严格的理论分析,我们证明了所提出的控制器导致系统误差动态一致最终有界。

英文摘要:

This paper presents a trajectory-tracking controller for multi-rotor unmanned aerial vehicles (UAVs) in scenarios where only the desired position and heading are known without the higher-order derivatives. The proposed solution modifies the state-of-the-art geometric controller, effectively addressing challenges related to the non-existence of the desired attitude and ensuring positive total thrust input for all time. We tackle the additional challenge of the non-availability of the higher derivatives of the trajectory by introducing novel nonlinear filter structures. We formalize theoretically the effect of these filter structures on the system error dynamics. Subsequently, through a rigorous theoretical analysis, we demonstrate that the proposed controller leads to uniformly ultimately bounded system error dynamics.
