针对登月软着陆问题,研究了无冲击的着陆轨道优化方法,阐述了极小值原理、蚁群算法、遗传算法和高斯伪谱法等算法用于登月软着陆轨道优化的思路。以极小值原理为例,采用燃料最优的性能指标,对登月软着陆轨道优化问题进行建模和求解。
In order to solve the problem of soft landing on the moon, the impact-free approach to landing orbit optimization is studied, and the concepts of minimum principle, ant colony optimization, genetic algorithm and Gaussian pseudospectral method are discussed. Taking the principle of minimum value as an example, the optimization of the lunar landing soft landing trajectory is modeled and solved by using the optimal fuel performance index.
