Distributed event-triggered control for multiagent systems with non-continuous communication faults and dynamic uncertainties

This paper investigates the adaptive event-triggered control problem for a class of nonlinear multiagent systems with non-continuous nonlinear communication faults and dynamic uncertainties. First, the non-continuous nonlinear communication fault mathematical model is proposed, and we design a fault detection method based on the boxplot method and a piecewise adaptive law to detect and compensate the impact of faults, respectively. Second, an event-triggered mechanism which does not need to design additional intermediate control signals is proposed to save communication resources. Then, the disturbance observer is used to solve the problem of dynamic uncertainties. Moreover, an event-triggered cooperative strategy is constructed, which can guarantee all signals of the closed-loop system are semiglobally uniformly ultimately bounded (SGUUB), and the tracking control performance can also be guaranteed. Finally, some simulation results confirm the effectiveness of the proposed control scheme.
