摘要: 为提高空间非合作目标近距离逼近轨迹的安全性,同时对接近时间及所消耗燃料进行优化,针对空间失效自旋非合作目标近距离接近问题,给出了失效卫星动态安全走廊,并以飞越逼近方式抵达走廊入口,进一步提出了飞越逼近轨迹优化方法。首先,在建立失效卫星自旋模型的基础上,规划了安全区与禁飞区,提出了2种安全走廊的选择依据。其次,采用飞越逼近作为近距离接近方式,以节约燃料和缩短逼近时间为目标对两脉冲机动模型进行优化,选择3种优化算法得到接近轨迹。仿真结果表明:安全走廊的选择与卫星失效自旋的形式、外形以及接口位置有关;在飞越逼近两脉冲机动模型的优化问题中,采用Fgoalattain算法进行优化处理更具优越性。

Abstract: In order to improve the safety of non-cooperative target's close-range approach trajectory, and optimize the approach time and fuel consumption at the same time, this paper designs the dynamic safety corridors of uncontrolled rotating satellite for the proximity to rotating non-cooperative target. The fly-by approach is chosen to reach the corridor entrance and the fly-by approach trajectory optimization method is proposed. First, based on the establishment of an uncontrolled rotating satellite spin model, the safety zone and the keep-out-zone are planned, and the basis for selecting two safety corridors is analyzed. Second, the fly-by approach is used as a close-range approach method, and with the goal of saving fuel and shortening the approach time, the two-pulse maneuver model is optimized and three optimization algorithms are selected to obtain the approach trajectory. The simulation results show that the choice of the safe corridor is related to the form, shape and interface position of the uncontrolled satellite spin. In the optimization problem of fly-by approaching two-pulse maneuver model, it is more advantageous to use the fgoalattain algorithm for optimization.

Key words: non-cooperative target, fly-by approach, safe corridor, trajectory optimization, close-range approach
