Cyber-physical systems are engineered systems whose operations are monitored, coordinated, controlled, and integrated by computing and communication cores interacting with humans and the physical environment. In this talk, will discuss some recent developments on control architectures for cyber-physical systems. Motivated by application projects in smart energy systems and goods transportation, we will consider the influence of local and partial plant state and model information on the synthesis problem. Some fundamental bounds relating global system performance with local information exchange and physical interactions will be introduced. How the 4G LTE and other communication infrastructures are integrated into the Stockholm Royal Seaport, a new sustainable city district, will be discussed. Details will be given on an emerging goods transportation system based on fleets of platooning heavy-duty vehicles utilizing V2V and V2I communications. Some preliminary results from a large-scale evaluation currently being performed on the highway road network in Northern Europe will be discussed, showing the fuel saving and transport efficiency potentials of the system but also some of the challenges with humans in the loop and technology transfer. The presentation will be based on joint work with many collaborators at KTH, Ericsson, and Scania.

He received MSc and PhD degrees in Electrical Engineering from Lund University. He has held visiting positions at UC Berkeley (1998-2000) and California Institute of Technology (2006-2007). His research interests are in networked control systems, hybrid and embedded system, and applications in transportation, energy, and automation systems. He has been a member of the IEEE Control Systems Society Board of Governors and the Chair of the IFAC Technical Committee on Networked Systems. He has been on the Editorial Boards of several journals, including Automatica, IEEE Transactions on Automatic Control, and IET Control Theory and Applications. He is currently on the Editorial Board of IEEE Transactions on Control of Network Systems and the European Journal of Control. He has been Guest Editor for special issues, including the one on "Wireless Sensor and Actuator Networks" of IEEE Transactions on Automatic Control 2011 and a current one on "Control of Cyber-Physical Systems" of the same journal. He was the General Chair of the ACM/IEEE Cyber-Physical Systems Week 2010 in Stockholm and IPC Chair of many conferences. He has served on the Executive Committees of several European research projects in the area of networked embedded systems. In 2009, he received the Best Paper Award of the IEEE International Conference on Mobile Ad-hoc and Sensor Systems. In 2009, he was also awarded Wallenberg Scholar, as one of the first ten scholars from all sciences, by the Knut and Alice Wallenberg Foundation. He was awarded an Individual Grant for the Advancement of Research Leaders from the Swedish Foundation for Strategic Research in 2005. He received the triennial Young Author Prize from IFAC in 1996 and the Peccei Award from the International Institute of System Analysis, Austria, in 1993. He received Young Researcher Awards from Scania in 1996 and from Ericsson in 1998 and 1999. He is a Fellow of the IEEE.
