Decentralized event-triggered broadcasts over networked control systems

Abstract

This paper examines event-triggered broadcasting of state information in distributednetworked systems. Event-triggering has the agent broadcast its state information when its local"error" signal exceeds a given threshold. We present a decentralized approach fordetermining event-triggering thresholds for nonlinear subsystems with the assumption that eachagent only has access to its local state. The main results of this paper show that ourdecentralized event triggering scheme guarantees the asymptotic stability of the entire networkedcontrol system. © 2008 Springer-Verlag Berlin Heidelberg.
