针对航天器入轨段,如何从多组初始轨道中选择一组最优轨道问题,进行了深入地理论分析,提出了一种基于灰色关联分析法的航天器初始轨道选优算法。根据航天器初始轨道的设计特点,创新地利用标称轨道作为属性基向量,解决了比较数列的生成问题,建立了灰色关联分析法的初始轨道选优决策数学模型以及求解的七个基本步骤,最后以一颗太阳同步轨道卫星为仿真算例,验证了数学模型和选优算法的合理性和正确性。
Aiming at spacecraft orbit, how to select a set of optimal orbits from multiple initial orbits is studied theoretically, and an initial orbit selection algorithm of spacecraft based on gray relational analysis is proposed. According to the design characteristics of spacecraft initial orbit, this paper uses the nominal orbit as the attribute basis vector to solve the generation problem of comparative series, and establishes the mathematical model of initial orbit selection of gray correlation analysis and the seven basic steps, Finally, a solar synchronous orbit satellite is used as a simulation example to verify the rationality and correctness of the mathematical model and optimization algorithm.
