混合遗传算法在远程交会轨道设计中的应用

远程交会是交会过程中能量消耗最大、时间消耗最长的阶段,属于多变量、多极值优化问题,传统的优化算法很难求得全局最优解。本文在对四冲量远程交会制导方法建模和分析的基础上,利用混合遗传算法对基于轨道要素的轨道设计进行了优化和仿真分析。仿真结果表明,遗传算法能够弥补传统优化算法的不足,对远程交会进行轨道优化设计。

The Application of Hybrid Genetic Algorithms in Orbit Design for Long -range Rendezvous

The long-range rendezvous phase consumes the most energy and time of the process,and it is a multi-variable,multi-extremum question of optimization.The traditional optimization algorithms are impossible to find the absolute extremum.Based on the model and analysis of the four-impulse guidance method of the long-range of rendezvous,this paper uses hybrid genetic algorithms to optimize and simulate the orbit elements of orbit design.Simulation results show that the hybrid genetic algorithms can optimize the orbit design of long-range rendezvous.
