Summary: Abstract--In this paper two approaches for reducing
communication traffic in a control network, namely, Model-
Based Networked Control Systems (MB-NCS) and event-
triggered control, are unified under a single framework. The
use of a model of the plant in the controller node not only
generalizes the Zero-Order-Hold (ZOH) implementation in
traditional event-triggered control schemes but it also provides
stability thresholds that are robust to model uncertainties. With
respect to MB-NCS, the stability conditions presented here do
not need explicit knowledge of the plant parameters as in
previous work but are given only in terms of the parameters of
the nominal model and some bounds in the model uncertainties.
The resulting framework is capable of increasing the update
time intervals compared with the individual approaches
considered in this paper.
