摘要
首先给出三角平动点附近的高阶解析解,并计算了三种特殊的运动类型。以日–地+月系三角平动点附近无长周期运动分量的拟周期轨道作为目标轨道,探讨轨道保持问题。针对三角平动点任务的轨道保持问题,我们研究了两种轨道保持策略,分别为多点打靶轨道保持与重构目标轨道的策略。计算中,将轨道控制问题转化为非线性规划问题,并以优化方法求解。仿真表明优化方法在轨道保持问题求解方面非常有效。
The high-order analytical solutions around triangular libration points are presented first,and then three typical kinds of orbits are computed. In this paper,the quasi-periodic orbits without long-periodic component in the Sun –Earth ＋ Moon system are taken as the nominal orbits. For the station-keeping problem,two strategies including multiple shooting stationkeeping strategy and the reconstruction of nominal orbit in real system are investigated. In the process of computation,the problem of stationkeeping is transformed into a nonlinear programming problem which can be solved by sequential quadratic programming method. Simulation results indicate that the optimization technique performs efficiently in the process solving the stationkeeping problem.
