Fixed-Time Event-Triggered Average Consensus of Nonlinear MASs With External Disturbances and Switching Topologies

This paper investigates the fixed-time event-triggered average consensus of nonlinear multi-agent systems (MASs) with external disturbances and switching topologies. Compared with the existing fixed-time event-triggered consensus results, we consider the nonlinear uncertainties, external disturbances and switching topologies simultaneously in this paper. Moreover, we extend the fixed-time event-triggered consensus results to the nonlinear MASs with switching topologies. The fixed-time average consensus is obtained via event-triggered control (ETC). Hence, the energy consumption and the frequency of the controller update can be reduced significantly. Furthermore, there is no Zeno behavior under the proposed average consensus control strategies.
