| 摘要: |
| 以二阶积分环节作为单体航天器动力学模型，在固定通信拓扑的基础上，假设每个航天器仅获取相邻航天器的速度位置信息，设计了分布式有限时间跟踪控制算法，并证明了算法的有效性。在该算法的基础上，采用了虚拟结构和阶级控制方法，使第一阶级航天器接受虚拟领队形成的虚拟结构信息，次级航天器接受上一级航天器信息，给出了有限时间编队方法，并通过数值仿真验证了该编队算法。 |

| Abstract: |
| In this paper,a dynamic model of single spacecraft is simulated by a double integrator and the communication topology is assumed fixed. Based on the information exchanges among neighbors,the distributed finite-time control protocol is designed and mathematically verified. Adopt the presented control protocol and combined with virtual structure and hierarchical protocol,the formation algorithm is designed,where in a group spacecraft on a lower level takes orders from spacecraft on a higher level. The numerical simulation is conducted,verifying the effectiveness of the proposed method. |
