Distributed Consensus for Discrete-Time Directed Networks of Multiagents with Time-Delays and Random Communication Links.

This paper is concernedwith the leader-following consensus probleminmean-square for a class of discrete-timemultiagent systems. The multiagent systems under consideration are the directed and contain arbitrary discrete time-delays. The communication links are assumed to be time-varying and stochastic. It is also assumed that some agents in the network are well informed and act as leaders, and the others are followers. By introducing novel Lyapunov functionals and employing some new analytical techniques, sufficient conditions are derived to guarantee the leader-following consensus inmean-square for the concernedmultiagent systems, so that all the agents are steered to an anticipated state target. A numerical example is presented to illustrate the main results. [ABSTRACT FROM AUTHOR]
