| 摘 要： | 在设计交会对接绕飞段的制导方案时,除考虑燃耗因素外,轨迹安全性设计指标也应予以满足。本文基于C-W方程的经典双冲量控制策略应用于绕飞段,在以往固定时间的双冲量控制研究的基础上,分别以燃耗、轨迹被动安全性、任务恢复执行能力和初始状态偏差作为独立约束条件,利用MATLAB计算机寻优,得到逐个独立约束下的控制时间的范围,同时采取逐层缩小的方式,最终获得了满足绕飞段轨迹安全性的设计要求以及满足多种约束条件的一种可以作为绕飞段优选的控制策略的双冲量控制方法。

| Abstract: | In order to design the control strategy for the fly-around phase in rendezvous and docking,not only the fuel consumption,but also the trajectory safety criterion must be considered.On the basis of the known two-impulse principle,this paper presents a two-impulse control method which integrates requirements for the fly-around phase.This method considers the fuel consumption,trajectory safety,mission recovery and initial condition biases as the independent constraints within one orbital period.Through searching the appropriate control time by MATLAB and adopting lessening in proper sequence,a two-impulse control law is designed to be a better control approach for the fly-around phase,which is associated with the trajectory safety criterion and with the given several constraints |
