摘　　要：在普适变量法求解Lambert转移问题基础上,提出基于NSGA-Ⅱ（non-dominated sorting genetic algorithm-Ⅱ）算法的轨道转移时间-能量优化问题解决方法：通过修改非优超排序方法和采用空间扩张策略对NSGA-Ⅱ算法进行了改进,运用约束支配的概念解决了约束条件下Pareto最优集分层困难的问题。仿真实验表明：改进的NSGA-Ⅱ算法能有效求解轨道转移时间-能量优化问题,且比原算法提高了Pareto前沿散布性能。Based on NSGA-Ⅱ Algorithm and Lambert orbit transfer problem that solved by using the concept of universal variables,a method was proposed to solve the constrained time-energy optimization of orbit transfer.The NSGA-Ⅱ Algorithm was modified by perfecting the fast non-dominated sorting method and expanding the aggregation of individuals.The concept of constrained-domination was applied to handle restriction.It was proved by simulation that the modified NSGA-Ⅱ Algorithm could solve the constrained time-energy optimization of orbit transfer effectively and had a better Pareto front than that of the original algorithm.
