摘要

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。

Design and Optimal Control on the No.3 Chang'e Landing Trajectory

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.

期刊介绍： "Experiment Science and Technology" is a comprehensive journal of natural sciences and engineering sponsored by the Sichuan Provincial Department of Education and the University of Electronic Science and Technology of China and the Sichuan Higher Education Association. It aims to report the development status, achievements or interim achievements of scientific research in natural sciences with talent training as the center; exchange research results and experience in the design, development, function development, maintenance management and supply management of instruments and technical equipment; explore common problems in the construction of laboratories at all levels and types, team building and improving the efficiency of instrument use from a technical perspective; explore new ideas, new ways and new measures for experimental teaching reform and innovation. The journal mainly has columns such as experimental technology, experimental teaching and teaching experiments, virtual simulation technology, laboratory environment and safety, experimental instrument development and maintenance, laboratory construction and management, and large-scale instrument management and sharing.
