摘　　要：自主构形重构是分布式卫星自主运行的典型任务。将构形重构问题分解为底层控制问题和上层规划问题,给出构形重构问题的统一描述,在一种递阶控制结构中探讨基于Agent的分布式卫星自主构形重构问题,并介绍基于ObjectAgent的实现框架。针对底层控制问题,提出卫星相对运动轨道调整的螺旋控制策略,并对燃料消耗量进行估计;针对上层规划问题,采用拍卖算法完成构形重构位置分配。最后通过一个仿真实例验证基于Agent的分布式卫星自主构形重构的可行性。The autonomous formation reconfiguration of Distributed Satellite Systems is one of the typical missions of autonomous control. Formation reconfiguration of distributed satellites was divided into two aspects： relative orbit control and overall planning. Furthermore, a uniform description of formation reconfiguration was presented. Then the problem of Agent-based autonomous formation recortfiguration was discussed in the hierarchical control architecture of distributed satellites, and the implementat/on framework in ObjectAgent is introduced. A novel spiral control scheme was raised for relative orbit regulation, and the cost budget was estimated. Auctioneering algorithm was adopted for position allocation. Simulation results show the effectiveness of Agent-based autonomous formation reconfiguration.
