针对空间多目标交会(拦截)平台停泊轨道设计问题,定义有效交会(拦截)区作为衡量平台交会(拦截)目标能力的指标,提出并建立了该类空间平台停泊轨道设计优化和分析模型,采用多岛遗传算法(MGA),以有效交会(拦截)区的最大化作为优化目标,以可交会(拦截)目标的数目和子飞行器轨道转移所需要的脉冲速度增量等为约束条件,对该类平台停泊轨道要素和子飞行器变轨时机进行综合设计优化。将上述模型和算法用于两空间平台设计中,一个是针对低轨2目标的交会平台,另一个是针对中轨3目标的拦截平台,得到合理的结果,表明所提出的设计优化模型以及选择的寻优算法是有效的。
Aiming at the problem of berthing orbit design for multi-purpose rendezvous and interceptor platform, the effective rendezvous (interception) zone is defined as an index to measure the rendezvous and interception capacity of the platform. The optimization and analysis model of mooring orbit design for such space platform is proposed and established. Multi-island genetic algorithm (MGA) is based on the maximization of the effective intercept (interception) area as the optimization objective. The constraints on the number of interceptable (intercepting) targets and the pulse speed increment required for the orbiter’s orbit transfer are used as constraints. Platform mooring orbit elements and sub-aircraft trajectory orbit change comprehensive design and optimization. The above models and algorithms are applied to the design of two space platforms. One is the rendezvous platform for low-orbit 2 targets and the other is the interception platform for medium-orbit 3 targets. The reasonable results show that the proposed design optimization model and the selection The optimization algorithm is valid.
