摘　　要：基于一致性算法,在有向通讯拓扑下,研究存在状态约束的多航天器系统分布式有限时间姿态协同跟踪控制问题.在仅有部分跟随航天器可以获取领航航天器状态,并且跟随航天器之间存在不完全信息交互的情形下,设计了分布式快速终端滑模面,提出了不依赖于模型的分布式有限时间姿态协同跟踪控制律.根据有限时间Lyapunov稳定性定理,证明了系统的状态在有限时间内收敛于领航航天器状态的小邻域内.最后通过仿真算例验证了所提出算法的有效性.Based on the consensus algorithm, a distributed finite-time attitude coordinated tracking control is proposed for multiple spacecraft systems with state constraint under the directed communication topology. A model-independent distributed finite-time attitude coordinated control algorithm is proposed by using the fast terminal sliding mode in the case that the leader spacecraft may only be available to a part of the follower spacecraft and/or with an incomplete information exchange among the follower spacecraft. The proposed control algorithm can guarantee that the follower spacecraft attitudes and angular velocities converge to a neighborhood of the leader spacecraft state in finite time based on the finite time Lyapunov theory. Simulation results show the effectiveness and feasibility of the proposed algorithm.
