Abstract
The defining characteristic of a networked control system (NCS) is
having one or more control loops closed via a serial communication
channel. Typically, when the words networking and control are used
together, the focus is on the control of networks, but in this article
our intent is nearly inverse, not control of networks but control
through networks. NCS design objectives revolve around the performance
and stability of a target physical device rather than of the network.
The problem of stabilizing queue lengths, for example, is of secondary
importance. Integrating computer networks into control systems to
replace the traditional point-to-point wiring has enormous advantages,
including lower cost, reduced weight and power, simpler installation and
maintenance, and higher reliability. In this article, in addition to
introducing networked control systems, we demonstrate how dispensing
with queues and dynamically scheduling control traffic improves
closed-loop performance
