Abstract: Model-Based Networked Control Systems (MB-NCS) use a model of the plant to
compensate for the lack of information between transmission times. This results in a significant
reduction of the bandwidth used for stabilizing the control system. Previously published stability
results for MB-NCS assume no quantization error. In this paper quantization is introduced for MB-
NCS. Sufficient stability conditions for static uniform, static logarithmic, and dynamic quantizers
for continuous linear time-invariant plants are derived. The results illustrate the effects of
quantization over the stability of MB-NCS and suggest a design model that starts with the non-
quantized MB-NCS. Copyright 2005 IFAC

1. INTRODUCTION
The use of networks as media to interconnect the
different components in control systems is rapidly
increasing. These systems are commonly referred to as
Networked Control System (NCS). In summary a NCS
is a control system in which a data network is used as
feedback media. The use of networked control systems
