Event-based control for networked systems: From centralized to distributed approaches

Networked control systems (NCSs) are spatially distributed systems in which sensors, actuators and controllers exchange information through a communication channel or network. The reduction in the amount of transmitted information has a relevant impact over the system's performance. In this regard, non-conventional communication rules, such as the event-based control, have been demonstrated to be effective. In this paper, some of these strategies are reviewed. We first focus on centralized NCSs, and then the distributed control for large-scale systems is studied. Finally, some of the results are applied to the formation control problem and implemented over an experimental setup.
