摘要
针对编队卫星在构型重构和构型失效重组时发生碰撞可能性最大的两种机动工况,采用数学规划的方法对其进行防碰撞规避准则、规避策略和控制方面的研究;并通过系统可控性证明出无径向推力相对于全向推力,也可以达到目标相位点只是燃料消耗得多。对编队构型失效重组工况中备份星机动前停泊位置,进入编队位置选择和启动时刻选择以及故障星离开编队后,目标轨道确定等问题通过数学仿真的形式予以解答。仿真结果表明,该研究方法真实可信、简便有效。
The mathematical programming method was used to research the collision avoidance rules, evasion and control strategies, in two moving conditions, including formation of satellite configuration reconstruction and configuration failure reorganization. The matrix shows that the target phase can also be achieved without radial thrust, more fuel compared with the whole thrust under the condition of system controllable just consuming much configuration failure reorganization, the issues regarding the backup satellite＇s parking location before moving, the location and moment selection of accessing into formation of satellite, and the failure satellite＇s target orbit were discussed. The simulation results show that the proposed method is true, simple and effective.
