摘要
针对空间非合作目标协同围捕任务,传统控制方法因博弈决策与编队执行相割裂,难以满足其强对抗、高动态下的实时响应与稳定包围需求。为此,提出一种基于微分博弈与预定时间控制的分层架构。该架构在上层构建目标-攻击者-防御者(TAD)博弈模型,通过在线求解纳什均衡以生成集群主卫星的最优包围轨迹;在下层则设计一种分布式的预定时间编队控制器,确保集群在预定时间内自主地实现编队构型建立、切换和保持。仿真结果表明:所提方法实现了上层博弈决策与下层编队控制的紧密协同,能够驱动卫星集群在预定时间内完成对目标的快速接近与稳定包围。
In cooperative encirclementmissions on non-cooperative space targets,it is hard for traditional control methods to satisfy the requirements ofreal-time response and stable encirclement under highly adversarial and dynamic conditions,primarily due to the decoupling ofgame decision-making and formation execution.To this end,a hierarchical architecture based on the differential game theory and prescribed-time control is proposed.The upper layer of this architecture constructs a target-attacker-defender(TAD)game model,generating the optimal encirclement trajectory for theswarm’s master satelliteby solving for the Nash equilibrium online.The lower layer,in turn,designs a distributed prescribed-time formation controller,ensuring that the swarm can autonomously achieve formation establishment,switching,and maintenance within a prescribed time.The simulation results demonstrate that the proposed method achieves tight coordination between the upper-layer game decision-making and lower-layer formation control,enabling the satellite swarm to complete a rapid approach and stable encirclement of the target within the prescribed time.
