Abstract
In this paper the control of linear plants, where the sensor is connected to a linear controller/actuator via a network is ad-
dressed. Both, state and output feedback, are considered and results are derived for both continuous and discrete plants. A
key idea is that knowledge of the plant dynamics is used to reduce the usage of the network. Necessary and sufficient condi-
tions for stability are derived as simple eigenvalue tests of a well-structured test matrix, constructed in terms of the update
time h, and the parameters of the plant and of its model. These tests are extended to include network delay as well.
Key words: Networked Control Systems, Stabilizability, Hybrid Systems, Minimum Feedback Information.
1. Introduction
The use of networks as a media to interconnect the dif-
ferent components in an industrial control system is rapidly
increasing. A network introduces bandwidth restrictions.
To overcome these bandwidth constraints several ap-
proaches have been proposed. Some of these include the
