针对嫦娥三号软着陆轨道设计与控制策略,结合动力学、微分方程等知识,主要建立多元非线性规划模型、模糊C均值聚类模型等,用于粗避障和精避障阶段优选着陆区的筛选,并通过对模型的定量和定性分析,得出嫦娥三号软着陆轨道设计与控制策略;又对第二阶段末端着陆器速度方向与竖直向下的夹角和其他控制过程进行敏感性分析和误差分析;最后对模型总体各阶段优缺点进行评价。

Targeted on Chang-e III soft landing orbit design and control strategy , some multivariate non-linear programming model and fuzzy C -means clustering models were established using the combination knowl-edge of dynamics , differential equations , and establish Kepler orbital dynamics with MATLAB and LINGO soft-ware to solve image processing and programming problem .Through the quantitative and qualitative analysis on the model, a conclusion of the Chang -e III soft landing orbit design and control strategies was drawn .The sen-sitivity analysis and error analysis for the second phase of the end of the lander and the vertical velocity direction downward angle and other control process were analyzed .Finally, the overalls model's merits and demerits of va-rious stages were assessed .
