摘要： 针对临近空间再入滑翔飞行器巡航段轨迹预测问题, 提出了控制律预测的轨迹预测算法。通过分析和推导轨迹预测中的未知量及研究归纳巡航段的飞行方式和控制律, 阐明轨迹预测的可行性;研究了平衡滑翔和跳跃滑翔2类轨迹的判别方法, 并在此基础上设计了控制律预测的轨迹预测算法。最后仿真验证了算法的有效性, 并研究了跟踪时长和起始点对轨迹预测精度的影响。结果表明该算法针对多种类型的轨迹都具有较高的预测精度;跟踪时长对预测精度影响较大, 而跟踪起始点影响较小。

Abstract: Aiming at the cruise segment trajectory prediction problem of near space reentry gliding vehicle, a trajectory prediction algorithm based on control law prediction was proposed. By analyzing and deriving the unknowns in the trajectory prediction and studying the flight modes and control laws of the cruising segment, the feasibility of trajectory prediction was clarified. The discriminating methods of two kinds of flight trajectories are studied: balanced gliding and jumping gliding. On this basis, a trajectory prediction algorithm based on control law prediction was designed. The algorithm was verified by simulation. The influence of tracking time and tracking starting point on trajectory prediction accuracy was studied. The results showed that the algorithm had high accuracy for different types of trajectories; the tracking time had a great influence on trajectory prediction accuracy; but the impact of tracking start point was small.

Key words: near space, trajectory prediction, control law, balance gliding, jumping gliding, forecasting accuracy
