Abstract
- 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.
