Event-Triggered Consensus Control for Multiagent Systems With Time-Varying Communication and Event-Detecting Delays

Abstract

In this paper, using event-triggered control method, we investigate the consensus problem of a distributed single-integrator network with time-varying communication and event-detecting delays. We propose a consensus protocol as well as event-triggering conditions only based on local information. The event-triggering condition for each agent is detected periodically to determine whether its state used in the local feedbacks of the network will be updated or not. A sufficient condition for reaching state consensus is given and the convergence analysis is conducted by Lyapunov methods. The presented result reveals the effect of the change rate of time delays on consensus. Moreover, an experimental example of a multiagent networked system consisting of two-wheeled mobile robots is conducted to demonstrate the feasibility and effectiveness of our proposed consensus protocol.
