摘要: 在交会对接飞行任务设计研究中必须首先确定目标航天器的轨道设计策略,研究了一种将目标航天器轨道维持和调相两种任务进行综合优化的策略。轨道维持的任务是使得目标航天器轨道的形状和位置符合交会要求,调相的任务是使目标航天器在轨道中的初始相位角符合交会要求。在考虑了交会对接发射窗口、交会终端约束条件下,将目标航天器轨道设计问题转化为一个非线性规划问题,应用序列二次规划方法对其进行了求解。仿真计算表明,这种方法既能以较少变轨次数满足交会对接任务要求,又能节省燃料,为空间交会对接任务规划提供了重要参考。

Abstract: A target spacecraft’s orbit must be designed for an orbit rendezvous mission. A new optimization approach is proposed for the mission by bringing both orbit keeping and phasing into effect simultaneously. Orbit keeping is to control the station and the shape of the target orbit, while orbit phasing is to make the initial phase angle desired for rendezvous. In this paper, considering such constraint conditions as the right ascension of ascending node and the inclination coresponding to the chaser spacecraft according to the rendezvous window, the resulting problem for the target orbit design is transformed into a nonlinear program-ming problem,then a sequential quadratic programming method is employed to obtain the solution. The calculation and simulation results show that application of this method not only can meet mission’s requirements with fewer maneuvers, but also can save propellant, so this work is useful for the mission planning of rendezvous and docking.

Key words: rendezvous and docking, orbital keeping, phasing, optimization
