嫦娥三号主减速段和快速调整段最优控制策略研究

Optimal Control Strategy of Chang’e-3 Main Reduce Phase and Quick Adjustment Phase

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.
