航天器轨道追逃微分对策研究综述

Survey on spacecraft orbital pursuit-evasion differential games

随着空间交会对接和操控技术的不断发展,航天器轨道追逃博弈研究日益受到重视,微分对策是其中重要的研究手段,本文对基于微分对策的航天器轨道追逃研究现状进行了评述.首先介绍了航天器追逃微分对策的基本问题形式,梳理了微分对策理论的发展脉络和当前研究热点.进一步分别对航天器轨道追逃定性微分对策、线性二次型微分对策、终端时间自由微分对策、不完全和不完美信息微分对策、脉冲推力微分对策的问题模型、求解方法和一般性结论进行了总结.最后展望了航天器轨道追逃博弈的后续研究方向.

Orbital pursuit-evasion(PE) of spacecraft has drawn increasingly significant attention from the research community in recent years.This paper surveys the state-of-the-art advances in solutions to the PE problem, particularly focusing on differential game theory methods. First, general mathematical descriptions of the PE game are presented and recent theoretical developments are discussed.Further, major results on spacecraft orbital PE differential games under a wide range of formulations are reviewed, including qualitative, linear quadratic, and free-time games, as well as a game with incomplete or imperfect information and one with impulsive thrust. Finally, we conclude with a discussion of open challenges and directions for future research on spacecraft orbital PE.
