Summary. In this article a class of networked control systems called Model-Based
Networked Control Systems (MB-NCS) is considered. This control architecture uses
an explicit model of the plant in order to reduce the network traffic while attempt-
ing to prevent excessive performance degradation. MB-NCS can successfully address
several important control issues in an intuitive and transparent way. In this arti-
cle the main results of this MB approach are described with examples. Specifically,
conditions for the stability of state and output feedback continuous and discrete sys-
tems are derived under different scenarios that include delay compensation, constant
and time varying update times, non-linear plants and quantization of the feedback
signals. In addition, a performance measure for MB-NCS with noise inputs is intro-
