摘要

研究了月球着陆器问题的最优控制解。本文的主要目的是研究以最小的燃料消耗保证着陆器从月球停泊轨道到月球表面软着陆的最佳轨道设计策略。通过制定最优控制问题,通过两个实例研究了月球着陆器的轨迹设计,其中软着陆问题的具体要求都纳入了问题的制定中。为了分析所提出的最优软着陆策略,本文简要地举例说明了数值模拟结果,结果表明,软着陆所需的速度以最小的燃料消耗实现。所研究的两种情况下月球着陆器问题最优解的计算方法在概念上简单有效。

Optimal trajectory design and analysis for soft landing on the moon from lunar parking orbits
This article studies the optimal control solution of the Moon-Lander problem. The main purpose of this article is to investigate the optimal strategy for trajectory design to ensure the soft landing of the lander from the Lunar parking orbit to the lunar surface with minimum consumption of fuel. The trajectory design of lunar lander is studied via two cases by formulating the optimal control problems, where specific requirements of this soft landing problem are all incorporated in the problem formulation. To analyse the proposed optimal strategies for a soft landing the paper briefly illustrates the numerical simulation results and it shows that the required velocity for the soft landing is achieved with minimum fuel consumption. The investigated computational methods for the optimal solutions of the Moon-Lander problem in both two cases are conceptually simple and efficient.
