摘要:
针对地球–火星之间的星际往返轨迹优化设计问题，本文采用了一种静态参数+动态优化的组合优化算法，进行全局一体化优化设计，通过大量的飞行数值仿真，得到了具体的最优方案。仿真结果表明，这种组合优化算法对求解星际往返轨迹优化问题具有良好的适用性和实际工程应用价值。
This paper globally optimized the 4-D flight trajectories between the Mars and the Earth by using a combined optimization algorithm. The optimization algorithm is comprised of static parameters and dynamic control laws. The optimal program of the 4-D flight trajectory between the Mars and the Earth is obtained by a great deal of flight numerical simulation. The numerical simulation re-sults show that this combined optimization algorithm is very useful regarding on global and inte-grative optimization of both flight trajectory and all design parameters.
