This article proposes event-triggered fault-tolerant attitude control strategies for nonlinear multispacecraft systems with disturbances, uncertainties, and input constraints. First, a dynamic event-based fault-tolerant attitude control algorithm is proposed to avoid continuous communication, where the dynamic and constant parameters are introduced to enlarge the trigger threshold, which improves resource conservation efficiency. Second, a self-triggered fault-tolerant attitude controller is constructed to avert continuous detection of events, indicating that continuous computing is not required and the computational burden can be reduced. Moreover, the proposed trigger mechanisms make the system have a positive interevent time, which shows the system is Zeno-free. Finally, simulations are provided to demonstrate the effectiveness of the developed controllers.
