Abstract
For attitude coordination tracking of spacecraft formation flying affected by external disturbances, actuator faults, and limited communication, this paper investigates a finite-time adaptive coordinated control law. To suppress the influence of external disturbances and actuator faults, an adaptive sliding mode controller is adopted. To reduce the communication between neighboring spacecraft, a distributed event-triggered control scheme is designed. Under the scheme, the communication channel only transmits information at the trigger instants that are decided by the predefined triggering condition. Based on the Lyapunov theorem, the stability of the closed-loop system can be proved. The effectiveness of the scheme is verified by simulation results.
