Networked control systems are made up of several computer nodes
communicating over a communication channel, cooperating to control a
plant. The stability of the plant depends on the end to end delay from
sensor to the actuator. Although computational delays within the
computer nodes can be made bounded, delays through the
communication network are generally unpredictable. A method which
aims to protect the stability of the plant under communication delays
and data loss, Model Based Predictive Networked Control System
(MBPNCS), has previously been proposed by the authors. This paper aims
to demonstrate the implementation of this type of networked control
system on a non-real-time communication network; Ethernet.
In this paper, we first briefly describe the MBPNCS method, then
discuss the implementation, detailing the properties of the operating
system, communications and hardware, and later give the results on the
performance of the Model Based Predictive Networked Control System
implementation controlling a DC motor.
