目的-本文旨在研究具有通信延迟的刚性卫星群的快速姿态协调控制问题。设计/方法/途径-基于行为控制方法，设计姿态控制系统，保证卫星群的姿态在有限时间内收敛到动态参考状态。为了提高控制系统的收敛速度和鲁棒性，提出了一种快速滑模控制方法。该算法同时考虑了通信时延、参数不确定性和外部干扰的影响，卫星群的通信拓扑可以是任意类型。数值模拟证明了分析结果。结果-尽管存在通信延迟，参数不确定性和外部干扰，闭环系统的稳定性可以成功地保证和所提出的控制策略是有效的，以克服这些意外现象的主题。
Purpose – This paper aims to investigate the fast attitude coordinated control problem for rigid satellite swarms with communication delays.Design/methodology/approach – Based on behavior‐based control approach, the attitude control system is designed to guarantee that the attitude of the satellite swarm converge to a dynamic reference state in finite time. A fast sliding mode is developed to improve the convergence rate and robustness of the control system. All the effects of communication delays, parameter uncertainties and external disturbances are taken into account simultaneously, and the communication topology of the satellite swarm can be arbitrary types. Numerical simulations are provided to demonstrate the analytic results.Findings – Despite the existence of communication delays, parameter uncertainties and external disturbances, the stability of the closed‐loop system can be successfully guaranteed and the proposed control strategies are effective to overcome these unexpected phenomena subject t...
