This paper studies a robust attitude coordinated control method for spacecraft formation flying system in the presence of external disturbances based on event-triggered control and sliding mode control. To decrease the communication frequency of the spacecraft formation flying system, a sliding mode coordinated controller without Zeno phenomenon is developed by using a novel triggering condition. For the first time, the proposed method addresses the problem that the existence of the closed-loop event-triggered control system solution in the classical sense may not be guaranteed due to the sliding mode surface with discrete variables fundamentally. The theoretical analysis and numerical simulation results demonstrate the effectiveness of the proposed control approach.

本文研究了一种基于事件触发控制和滑模控制的存在外部扰动的航天器编队飞行系统的鲁棒姿态协调控制方法。为降低航天器编队飞行系统的通信频率，利用新颖的触发条件，开发了一种无芝诺现象的滑模协调控制器。该方法第一次从根本上解决了由于具有离散变量的滑模面而不能保证经典意义上的闭环事件触发控制系统解存在的问题。理论分析和数值模拟结果证明了所提出的控制方法的有效性。
