本文提出了一种考虑风向影响的无人机在三维给定两点间导航的最优制导方法。所提出的最小化成本函数涉及到行程时间和控制能量的权重。导出了最优成本的解析表达式，得到了一个四阶多项式，其正实数根对应于最优旅行时间。结果表明，在风加速度恒定的情况下，该优化问题等价于零努力脱靶/零努力速度最优制导方法。通过不同风力条件下的仿真，给出了交会与拦截问题的实例分析。
This article presents an optimal guidance approach for unmanned aerial vehicle 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 optimal guidance approach for the case of a constant wind acceleration. Case studies for rendezvous and intercept problems are shown through simulation examples for different wind conditions.
