On a small-gain approach to distributed event-triggered control

In this paper the problem of stabilizing large-scale systems by distributed controllers, where the controllers exchange information via a shared limited communication medium is addressed. An event-triggered sampling scheme is proposed, in which each system decides when to transmit new information across the network based on the crossing of some error threshold. Stability of the interconnected large-scale system is inferred by applying a generalized small-gain theorem. © 2011 IFAC
