Criterion for Winning Closed-Loop Strategies in Orbital Games
摘要
Abstract
Distance regulation and maintenance between a spacecraft and a non-cooperative target is a critical aspect of space missions,which can be modeled as a closed-loop orbital game under incomplete information.The existence of winning strategies in such games is influenced by multiple key decision variables,with complex coupling relationships among them.To address this issue,this paper proposes a quantitative discriminant condition based on the decision-making period of both players,the maximum impulsive control magnitude,the relative distance to the target,and the allowable tolerance.Under this condition,a closed-loop feedback strategy can be designed to maximize the game performance metric,in terms of the reachability and maintainability of the target region.Subject to constraints on decision-making period and maneuverability,the proposed optimal strategy for orbital game consists of two phases:(1)a tactical approach phase,which enables the spacecraft to approach the target region rapidly,and(2)a tactical station-keeping phase,which stabilizes the spacecraft within the region.Finally,numerical simulations validate the effectiveness of the proposed quantitative discriminant conditions.关键词
