Zusammenfassung
Netzwerke, die ursprünglich aus der Bürokommunikation stammen und auf dem Quasi-Standard des Internetprotokolls beruhen, werden in der Automatisierungstechnik immer beliebter. Dieser Beitrag untersucht, inwieweit solche Netzwerke auch für regelungstechnische Aufgaben eingesetzt werden können. Anhand einer Fallstudie wird gezeigt, welche Auswirkungen die stochastischen Eigenschaften des Netzwerks auf eine Regelung haben und wie die Regelgüte verbessert werden kann.
Abstract
Office networks based on the de-facto standard of the Internet Protocol are gaining acceptance in various automation domains. This article investigates the possible applicability of such networks for control engineering tasks. A case study demonstrates how the stochastic properties of the network affect a control loop and how the quality of control can be improved.
