摘要

This paper focuses on the input–output finite-time consensus problem for switched multi-agent systems (SMASs) via observer-based event-triggered control. A hybrid event-triggered strategy is introduced that effectively eliminates Zeno behavior. The trigger threshold dictates the quantity of sampled data transmitted to the controller. To address unmeasurable or unobservable system states, an event-triggered observer is designed. Then, an observer-based control protocol is constructed to achieve the input–output finite-time consensus of the SMASs with time-varying delay. Furthermore, sufficient conditions for the finite-time boundedness and input–output finite-time stability of asynchronous SMASs are established by constructing a Lyapunov-Krasovskii functional and designing agent-dependent switching laws with finite-time constraints. A numerical simulation is conducted to verify the validity of the results.
