Abstract
The emergence of networked embedded systems and sensor/actuator networks has given rise to advanced monitoring and control applications, where a large amount of sensor data is collected and processed in real-time in order to activate the appropriate actuators and achieve the desired control objectives. However, in situations where faults arise in one or more of the sensing devices, this may lead to a serious degradation in performance or to an overall system failure. The goal of this presentation is to motivate the need for health monitoring, fault diagnosis and security of complex distributed dynamical systems and to provide a methodology for detecting and isolating multiple sensor faults in a class of complex nonlinear dynamic systems. The detection of faults in sensor groups is conducted using robust analytical redundancy relations, formulated by structured residuals and adaptive thresholds. Various estimation algorithms will be presented and illustrated, and directions for future research will be discussed.
Biography
Marios M. Polycarpou is a Professor of Electrical and Computer Engineering and the Director of the KIOS Research Center for Intelligent Systems and Networks at the University of Cyprus. He received the B.A. degree in Computer Science and the B.Sc. degree in Electrical Engineering both from Rice University, USA in 1987, and the M.S. and Ph.D. degrees in Electrical Engineering from the University of Southern California, in 1989 and 1992 respectively. In 1992, he joined the University of Cincinnati, Ohio, USA, where he reached the rank of Professor of Electrical and Computer Engineering and Computer Science. In 2001, he was the first faculty to join the newly established Department of Electrical and Computer Engineering at the University of Cyprus, where he served as founding Department Chair from 2001 to 2008. His teaching and research interests are in intelligent systems and networks, automation and computational intelligence, fault diagnosis and distributed systems. Dr. Polycarpou has published more than 220 articles in refereed journals, edited books and refereed conference proceedings, and he is the holder of 3 patents. Prof. Polycarpou is a Fellow of the IEEE and currently serves as the President of the IEEE Computational Intelligence Society. He has served as the Editor-in-Chief of the IEEE Transactions on Neural Networks and Learning Systems between 2004-2010. He has been invited as Keynote Plenary Speaker at 15 international conferences during the last three years and is currently an IEEE Distinguished Lecturer in computational intelligence. He participated in more than 50 research projects/grants, funded by several agencies and industry in the European Union, the United States, and by the Research Promotion Foundation of Cyprus. He has recently been awarded the prestigious European Research Council (ERC) Advanced Grant by the European Commission.
