Networked Control Systems (NCS) are distributed control systems where the
sensor signals to the controllers and the control data to the actuators are enclosed
in messages and sent over a communication network. On the one hand, the
design of an NCS requires ensuring the stability of the control system and
achieving system response that is as close as possible to that of an ideal system
which demands network resources. On the other hand, these resources are
limited and have to be allocated efficiently to accommodate for future system
extensions as well as applications other than control purpose. Furthermore the
NCS design parameters for the control system messages and the message
transmission over the network are interdependent. In this thesis, we propose
&ldquo / Integrated NCS Design (INtERCEDE: Integrated NEtwoRked Control systEm
DEsign)&rdquo / a novel algorithmic approach for the design of NCS which ensures the
stability of the control system, brings system response to that of an ideal system
v
as close as desired and conserves network bandwidth at the same time. The core
of INtERCEDE is a bargaining game approach which iteratively calculates the
message parameters and network service parameters. Our experimental results
demonstrate the operation of INtERCEDE and how it computes the optimal
design parameters for the example NCS.
