Professor Karl-Erik Årzén, Lund University, SwedenKarl-Erik Årzén received his M.Sc. in Electrical Engineering and PhD in Automatic Control from LundUniversity in 1981 and 1987, respectively. He was appointed as full professor in automatic control and LundUniversity in 2000. He has also worked for ABB Corporate Research during 1992-1994. His research interests include real-time systems, real-time and embedded control, control of computer software systems, discrete event and sequential control. He is the leader of the Control for Embedded Systems cluster within the EU/IST Network of Excellence ARTIST2 since 2004 and a member of the management group of LUCAS at LundUniversity since 1999. He is currently also involved in the EU Integrated Project RUNES (Reconfigurable Ubiquitous Networked Embedded Systems) on wireless networked embedded systems.

Wireless sensor networks in control and automation.Wireless networked embedded systems are becoming increasingly important in a wide area of technical fields. In this presentation we present recent results on design and control of these systems developed within the project Reconfigurable Ubiquitous Networked Embedded Systems (RUNES), which is an European Integrated Project with the aim to control complexity in networked embedded systems by developing robust and scalable middleware systems. New components for control under varying network conditions are discussed for the RUNES architecture. The complexity of the closed-loop system is increased due to the coupling with the disturbances introduced by the communication system. The network may introduce additional delays, jitter, data rate limitations, packet losses etc. Experimental work on integration test beds that demonstrates these results is shown together with motivating links to the RUNES disaster relief tunnel scenario.
