Distributed Event-triggered Output Consensus for General Linear Heterogeneous Multi-Agent Systems with System Uncertainties

This paper is devoted to study the distributed event-triggered output consensus (ETOC) of heterogeneous multi-agent systems (MASs) with general linear dynamics subject system uncertainties over digraphs. To account for practical case where only inaccurate model available, a scheme studied based on internal principle such that error approaches small adjustable bounded set related mismatch level between accurate and model. improve triggering performance, novel resilient state-independent threshold introduced into state-dependent threshold, which endows piecewise continuous mixed feature reset greater value when an event triggered. Within proposed ETOC scheme, circumvent neighbouring state exchange ensured. By theoretical analysis stability Zeno behavior, feasibility guaranteed. Numerical simulations are carried out.
