摘要
在嫦娥三号软着陆轨道优化设计中,以燃料最省和着陆安全为主要目标,结合实测数据和实际要求,对嫦娥三号软着陆过程进行分析,并对各阶段控制策略进行规划,运用MATLAB对嫦娥三号的着陆轨道进行了模拟优化设计,最终确立最优落月轨迹.通过建立误差分析和敏感性分析模型,对设计的着陆轨道和控制策略进行可行性分析,获得影响着陆器安全着陆的主要因素,为今后更深层次的月球探测和轨道优化提供理论依据和方法支持.
In order to achieve the main target of saving the fuel and landing safety, the CE-3 soft landing process is analyzed and the control strategy of the various stages is planned, combining with the measured data and the actual requirements of the goddess of the moon. MATLAB is applied to the CE-3 landing trajectory and the optimal landing trajectory is obtained, finally the optimal trajectory falling moon is built. When error analysis and sensitivity analysis of the model is established, we analyze the feasibility of the landing trajectory and control strategy to obtain the main factors influencing the lander safely, which can support the theoretical basis and methods for the further lunar exploration by using this method mentioned in this paper.
