| 摘 要： | 对利用小推力发动机将月球探器从双曲线轨道转移到圆轨的燃料最省转移问题，进行了研究，首先，将问题分解为双曲线到椭圆的转移和从椭圆到目标圆轨道的转移两步，然后，分别利用遗传算法解决了冲量假设下的最估转移、小推力加速民政部下从双曲线到椭圆的转移轨道优化，以及转移时间有约束情况下的从椭圆到圆轨道的转移轨道优化问题。

| Abstract: | The minimum-fuel-consumption problem of low-thrust orbit maneuver from a hyperbolic orbit to a circular orbit is studied. At first, the problem is divided into two partsorbit maneuver from a hyperbolic orbit to an elliptic orbit and orbit maneuver from an elliptic orbit to a circular orbit. Then, a genetic algorithm is used to solve the optimization problem in the cases of impulse assumption, low-thrust orbit maneuver from a hyperbolic orbit to an elliptic orbit, and low-thrust orbit maneuver from an elliptic orbit to a circular orbit with transfer time constraint. |
