| 摘 要： | 本文提出一种用于非合作目标惯性指向轴位置捕获的绕飞方法。该方法依据实时相对位置和目标位置确定绕飞坐标系；在绕飞坐标系中，分别采用扇形轨迹和直线轨迹设计了两类接近轨迹规划策略，利用相对位置和目标位置间的夹角进行规划策略选择，以规划得到过渡目标位置，并采用CW制导进行过渡目标位置的接近控制；为保证绕飞过程中相对测量敏感器始终有效测量，还设计了姿态指向控制律使追踪航天器x轴指向目标航天器。数学仿真校验了所设计方法的有效性。

| Abstract: | A fly-around method applied to capture position on inertia axis of a non-cooperative target is proposed. Firstly, a fly-around frame is defined using real relative position and target position. Secondly, two kinds of scheme for approaching path design are described, one named sector scheme and another named beeline scheme. According to the angle between real relative position and target position, one of the two schemes is selected to produce a transitional target position, and CW guidance law is applied for approaching the position. Thirdly, an attitude control law is designed for keeping the x axis of chaser pointing to the non-cooperative target. Finally, the efficiency of the fly-around method is validated by a simulation. |
