Event-triggered fault tolerant control for spacecraft formation attitude synchronization with limited data communication

摘要

This paper investigates the leader-following attitude consensus problem of a group of n-th spacecrafts with actuator fault and limited data communication, where the event-triggered based sending mechanism is considered to decrease communication burthen. In this design, unknown actuator faults and external disturbances are considered, and an event-triggered based adaptive distributed cooperative attitude control law is developed to solve the multiple spacecrafts formation control problem. It is shown that leader-following attitude synchronization can be achieved under the designed event-triggered control law. Finally, a simulation example is provided to illustrate the effectiveness of the proposed attitude coordination control techniques. (C) 2018 European Control Association. Published by Elsevier Ltd.
