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 consistency algorithm, under the directional communication topology, the state space constrained multi-spacecraft distributed finite-time attitude coordinated tracking control problem is studied, and the state of the pilot spacecraft can be obtained only by following the spacecraft, In the case of incomplete information interaction, a distributed fast terminal sliding-mode surface is designed and a model-independent distributed finite-time gesture cooperative tracking control law is proposed. According to the finite-time Lyapunov stability theorem, the state of the system Which converges to the pilot spacecraft’s state within a finite time.Finally, the simulation example is used to verify the effectiveness of the proposed algorithm.
