摘要 为实现载人登月任务中载人飞船在固定的时间内以最少的燃料消耗完成与登月舱的全相位降轨远程交会,研究月球捕获制动和快速降轨远程交会一体化制导的问题.基于Lambert变轨,综合考虑捕获制动及远程交会过程的时间约束、速度增量约束和终端约束等,设计出多脉冲捕获制动和远程交会一体化制导规划模型,并利用遗传算法和单纯形算法相结合的混合遗传算法对规划模型进行求解.通过仿真算例对混合遗传算法、遗传算法和单纯形算法进行比较,表明混合遗传算法在提高求解质量方面的优越性.进一步,对捕获制动时载人飞船和登月舱在固定相位下的不同制导时间和固定时间下的不同初始相位的情况进行了对比分析和打靶仿真,表明所提出的月球捕获制动和远程交会一体化制导算法的强适应性. Aiming at the fact that the manned spacecraft completes the all-phase orbit descent and far-range rendezvous of the lunar module within a fixed period with the least fuel cost during the manned mission to the moon,we study the integrated guidance of lunar capture braking and quick orbit descent and far-distance rendezvous.Based on Lambert rendezvous method,a multi-impulse lunar capture braking and far-range rendezvous planning model is designed by comprehensively considering capture braking and far-range rendezvous time constraints,speed increment constraints,and terminal constraints among others.A hybrid genetic algorithm combining genetic algorithm and simplex algorithm is used to solve the planning model.By comparing the hybrid genetic algorithm,genetic algorithm and simplex algorithm through simulation examples,it indicates the superiority of hybrid genetic algorithm in improving the quality of solution.Furthermore,we conduct simulations of multiple target practice and comparative analyses of manned spacecraft and lunar module starting at any initial phase angle within a fixed time and at a fixed initial phase within different time when achieving capture braking.These simulation results indicate the strong adaptability of the integrated guidance algorithm of lunar capture braking and far-range rendezvous proposed in this paper.
