Abstract

The movement and fuel consumption of the No. 3 Chang'e during the landing procedure on the near moon point and remote moon point is researched as well as the trajectory design and optimal control strategy is given. Firstly,the movement trajectory is projected to a plane at the remote moon point direction. Coordinate axis is established based on the zero longitude and zero degree latitude. The movement of the No. 3 Chang'e in near moon point is considered as uniform circular motion. Then the location of near moon point and remote moon point can be calculated. Subsequently,the minimal fuel consumption is set as the target variable to compute the optimal driving force in the case of the minimal consumption.

嫦娥三号着陆轨迹设计与最优控制

研究了嫦娥三号在近月点和远月点着陆过程中的运动和燃料消耗，给出了轨迹设计和最优控制策略。首先，将运动轨迹投影到远月点方向的平面上。以零经度和零纬度为基础建立坐标轴。嫦娥三号在近月点的运动被认为是匀速圆周运动。然后计算出近月点和远月点的位置。然后以最小油耗为目标变量，计算最小油耗情况下的最优驱动力。
