Abstract

 Cyber-Physical Systems (CPS) are very common and are becoming ubiquitous.  CPS depend on the seamless integration of computational algorithms and physical components and are characterized by large numbers of tightly integrated heterogeneous components in a network, which may expand and contract dynamically. The control of such systems presents significant challenges and requires designs drawn from approaches such as those in traditional control, computer science, hybrid control systems, discrete event systems, and networked control. In addition, robustness, reliability and security issues for reconfiguring dynamical systems must also be addressed.

Passivity and dissipativity are general, “energy like” concepts that may be used to guarantee properties, such as stability, in complex heterogeneous interconnected systems that are changing dynamically. Passivity and QSR-dissipativity approaches have been proposed to control CPS, together with Lyapunov approaches and symmetry concepts. We use passivity indices, which provide a measure of the degree of passivity, to generalize known results in interconnected systems. Several results for continuous, discrete, switched and networked systems, together with event triggered control architectures will be discussed with emphasis on the control of CPS.

Biography

Panos Antsaklis is the Brosey Professor of Electrical Engineering at the University of Notre Dame. He is a graduate of the National Technical University of Athens, Greece, and holds MS and PhD degrees from Brown University. His research addresses problems of control and automation and focuses on control systems that exhibit high degree of autonomy. His recent research focuses on the design of Cyber-Physical Systems using passivity and dissipativity. He had co-authored three research monographs on discrete event systems and on model-based control of networked systems, two graduate textbooks on Linear Systems and has co-edited six books on Intelligent Autonomous Control, Hybrid Systems and Networked Embedded Control Systems. He is IEEE, IFAC and AAAS Fellow, the 2006 recipient of the Engineering Alumni Medal of Brown University and a 2012 honorary doctorate recipient from the University of Lorraine, France. He is the Editor-in-Chief of the IEEE Transactions on Automatic Control.
