| 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。 |

| Abstract: |
| 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 reconfiguration was discussed in the hierarchical control architecture of distributed satellites, and the implementation 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. |
