摘要: 为了满足应急轨道机动过程中测控约束和时间、燃料资源等各方面的要求 ,提出了一种变轨方案快速设计算法.给出了适用于变量搜索的轨道机动变轨模式,将变轨 方案快速设计问题转化成了约束优化问题;建立了完整的测控约束数学模型和对测控约束的 处理算法;然后利用遗传算法搜索出了同时满足测控约束条件和优化目标的变轨方案.算例 表明,利用此算法设计得到的变轨方案,能够满足应急轨道机动任务的需要.

Abstract: A quick algorithm for designing emergency orbital transfer scheme that can meet the requirements of measure, fuel and time during emergency orbita l transfer was presented. The orbital transfer mode suitable for variable search was given. The question of designing orbital transfer scheme quickly was transf ormed into the question of restricted optimization. And the entire mathematics m odel of measure restrictions was established and the corresponding algorithm for measure restrictions was presented. Orbital transfer scheme, that is required n ot only to meet measure restrictions, but also to achieve optimal goal, was foun d by using genetic algorithm. Cases of calculation show that the orbital transfe r schemes designed by using this quick algorithm can meet the need of emergency orbital transfer mission.
