Abstract: In this paper, we apply the concept of Intermittent Feedback to a class of networked
control systems known as Model-Based Networked Control Systems (MB-NCS). We begin by
introducing the basic architecture for model-based control with intermittent feedback, then
address the case with output feedback (through the use of a state observer), providing a full
description of the state response of the system, as well as a necessary and sufficient condition for
stability in each case. Examples are provided to complement the theoretical results. Extensions
of our results to cases with nonlinear plants are also presented. Finally, we investigate the
situation where the update times and h are time-varying, first addressing the case where they
have upper and lower bounds, then moving on to the case where their distributions are i.i.d or
