航天器自主交会运动轨迹的控制

本文所提出的距离速率控制算法,使交会轨迹在轨道坐标系内为一条方位可选的稳态直线,满足软交会要求,而推力及测量系统配置很简单。用相平面方法论述了稳态直线轨迹的稳定性和收敛域;给出了算法中的可调参数的一些选值准则和曲线、三维运动的控制及推力斜装的效果、以及计算机模拟结果。

SPACECRAFT RENDEKVOUS TRAJECTORY CONTROL

The proposed Range-Rate Control Algorithm gives rise to a staionary straight line rendezvous trajectory in the orbital coordinate system, which meets the so called soft rendezvous requirements. The position of the trajectory is determined by a selectable parameter in the algorithm. The related measurement scheme is very simple, and the only propulsion in the algorithm is fixed to the direction of the line-of-sight or forms a constant anagle with it. Both continuous and interrupted regimes of the propulsoin are acceptable. The phase plane method has been used to analyse the local and global stability of the stationary trajectory. Some engineering aspects as well as the computer simulations of the algorithm have been introduced.
