航天器短期规避路径规划研究

Route planning for spacecraft collision avoidance maneuver with short-term encounters

针对在轨航天器主动防护的问题,对航天器直接规避路径规划和航天器规避-返回路径规划进行了研究,建立了规避-返回轨道规划问题的脉冲式最优轨迹非线性规划模型,利用主矢量理论和序列二次规划算法对问题进行了求解。通过数值仿真,揭示了航天器规避机动时刻与所需燃料、分离距离与所需燃料以及不同返回时间与所需燃料的规律,得到了对航天器主动防护研究有意义的结果,同时可为工程应用提供相关参考。

Aiming at the problem of spacecraft active protection,the route planning for collision avoidance maneuvering and collision avoidance maneuver-return was investigated.Using the nonlinear programming theory,an optimal impulse spacecraft collision avoidance maneuver and return route planning model was established.And using the primary vector theory and Sequential Quadratic Programming（SQP） to solve this problem.The simulation for the route planning was performed.The simulation results indicate the laws of fuel guantity required vs separation time,fuel guantity required vs miss distance,fuel guantity required vs return time.The engineering proof is provided for spacecraft collision avoidance maneuvering route planning by the research results.
