Abstract :
PID controllers are the most widely used control scheme in industry. Traditionally these controllers have been implemented in analog or digital form on specifically dedicated communication links. However, there has been significant recent interest into deploying control over general purpose communication channels, which allow one to transmit data, voice and control signals. Naturally the successful design of such a networked control system necessitates a blend of techniques which reflect both control and communication aspects. The present work examines the effect of channel noise (or, equivalently, of channel capacity) on closed loop system behaviour. It is shown, and experimentally verified, how performance can be optimized via signal coding
