Abstract

The article presents a method for designing the trajectory of the UAV in space, taking into account the restriction on control. The chosen optimal controls are namely normal overload with restrictions, tangential overload with restrictions, and lateral overload. The Pontryagin maximum principle allows the transition of the optimal control problem to a boundary value problem. The parameter continuation method is applied to solve the boundary problem. The article results reveal reference trajectories in different cases of UAV landing. This result allows the design of reference trajectories for the UAV to attain the highest landing efficiency.

考虑控制约束和着陆速度的无人机着陆轨迹设计
本文提出了一种考虑控制约束的无人机空间飞行轨迹设计方法。所选择的最优控制方法是有限制的正常过载、有限制的切向过载和横向过载。庞特里亚金极大值原理允许将最优控制问题转化为边值问题。采用参数延拓法求解边界问题。本文的研究结果揭示了不同情况下无人机着陆的参考轨迹。这一结果允许无人机参考轨迹的设计达到最高的着陆效率。
