This study presents a method to adjust the waypoints of an unpowered air vehicle to compensate for the influence of wind on the trajectory. A framework combining preflight waypoint planning and inflight waypoint adjustment is proposed. In the offline planning phase, optimal trajectories under various wind profile combinations are generated by using a direct optimization method. Waypoints are extracted from the obtained trajectories for each wind condition. Then, deviations of each waypoint due to wind from the corresponding waypoint on the trajectory for a zero-wind case are obtained; these deviations are used to construct the models of waypoint deviation as functions of wind speed and direction via least-squares regression. In the online adjustment phase, the wind-compensated waypoint is computed using the waypoint deviation model and the estimated wind velocity. A nonlinear six degrees-of-freedom simulation, incorporating a guidance and control system and a realistic wind profile, is performed to demonstrate the effectiveness of the proposed waypoint management framework.

使用在线航路点校正的无动力飞机风补偿框架

本研究提出了一种调整无动力飞行器航路点的方法，以补偿风对轨迹的影响。提出了一种结合飞行前航路点规划和飞行中航路点调整的框架。在离线规划阶段，使用直接优化方法生成各种风廓线组合下的最佳轨迹。从获得的每个风况的轨迹中提取航路点。然后，获得由于风引起的每个航路点与零风情况下轨迹上相应航路点的偏差；这些偏差用于通过最小二乘回归构建作为风速和风向函数的航路点偏差模型。在在线调整阶段，使用航路点偏差模型和估计的风速计算风补偿航路点。执行非线性六自由度模拟，结合制导和控制系统以及真实的风廓线，以证明所提出的航路点管理框架的有效性。
