摘要
针对嫦娥三号软着陆轨道设计及控制策略,运用了开普勒定律、能量守恒定律、轨道动力学抛和物线拟合原理等方法,分别建立了近远月点速度求解、主减速动力学、曲线拟合和数值仿真敏感度分析等模型,通过运用Matlab等软件编程画图,得出了着陆准备轨道的近远月点的位置以及其速度,还得出了着陆轨道方程,最后对着陆轨道和控制策略分别进行了详细敏感度分析。
Methods of Kepler＇s Laws, Energy Conservation Law, Orbital Dynamics and Parabola Fitting Theory are used in the soft landing design and control strategy for Chang-e III which has established the velocity solution models at perilune and apolune, the main speed reduction kinetics model, sensitivity analyzing models of curve fitting and numerical simulation, etc.. With drafting programmed by Matlab and some other software, the location and velocity of landing orbit at perilune and apolune can be worked out and the equation of landing track can be acquired. Finally, detailed sensitivity analyses are given on the landing track and control strategies respectively.
