论文摘要
本文考虑到风影响，本文为在3D中的两个给定点之间进行了无人机导航的最佳指导方法。提议的成本函数要最小化涉及行程时间和控制能量的加权。得出了最佳成本的分析表达式，该成本产生了四阶多项式，其正真根对应于最佳行进时间。优化问题表明，对于恒定风加速度的情况，优化问题等效于零劳 - 无数/零富效性（ZEM/ZEV）最佳指导方法。 Rendez-Vous和截距问题的案例研究通过模拟示例显示了不同的风条件。
This paper presents an optimal guidance approach for a UAV navigation between two given points in 3D considering the wind influence. The proposed cost function to be minimized involves the weighting of the travel time and the control energy. An analytical expression is derived for the optimal cost yielding a fourth-order polynomial whose positive real roots correspond to the optimal travel times. The optimization problem is shown to be equivalent to the Zero-Effort-Miss/Zero-Effort-Velocity (ZEM/ZEV) optimal guidance approach for the case of a constant wind acceleration. Case studies for the rendez-vous and the intercept problems are shown through simulation examples for different wind conditions.
