| 摘 要： | 利用航天器之间不同的大气阻力可以产生半长轴偏差以实现沿航迹漂移控制。沿航迹漂移气动控制采用时间最优控制律。为了适应天地大回路控制要求，所设计的时间最优控制律可离线实现。在考虑状态测量误差以及大气密度误差等不确定性因素条件下，对使用时间最优控制律的沿航迹漂移控制进行了仿真分析，仿真结果表明：沿航迹漂移的控制精度优于100m。

| Abstract: | Utilizing semimajor axis deviation produced by the different atmospheric drag between spacecrafts can accomplish along-track separation control.Along-track separation aerodynamic control follows the principle of time-optimal control law that can be off-line operation to meet the need of ground-in-loop control.Besides,in the paper simulation analysis is carried out on the along-track separation control under time-optimal control law considering uncertainty conditions such as measurement errors of state and o... |
