摘要:
研究嫦娥三号(CE-3)软着陆过程中的主减速段和快速调整段这两个阶段的最优控制策略，根据牛顿第二定律，建立针对这两个阶段的燃耗最优模型，得到最优控制策略。误差分析和敏感性分析说明了本文所用方法的有效性。
To study the optimal control strategy of the main reduction phase and quick adjustment phase in the process of Chang’e-3 soft landing, we established the optimal model for these two phases ac-cording to the Newton’s second law. The error analysis and sensitivity analysis were made to show the efficiency of the method used in this paper.
