| 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. |
