LIDS Seminar Series

Supervisory Control of Discrete Event Systems: A Retrospective and Two Recent Results on Security and Privacy

February 13, 2018 @ 3:00 pm - 4:00 pm

Stephane Lafortune (University of Michigan)

32-141

Abstract

Lafortune will begin with a brief retrospective of the theory of supervisory control of discrete event systems, initiated in the seminal work of Ramadge & Wonham over 30 years ago, and compare it with recent work in formal methods in control. He will then present results from his group on two problems: (i) sensor deception attacks in the supervisory control layer of a cyber-physical system; and (ii) obfuscation of system secrets by insertion of fictitious events in the output stream of the system. In each case, he will describe the group’s solution procedure, which is based on synthesizing a discrete game structure that embeds all valid solutions.

Biography

Stéphane Lafortune is a professor in the Department of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor, USA. He obtained his degrees from École Polytechnique de Montréal (B.Eng), McGill University (M.Eng), and the University of California at Berkeley (PhD), all in electrical engineering. He is a Fellow of IEEE (1999) and of IFAC (2017).

Lafortune’s research interests are in discrete event systems and include multiple problem domains: modeling, diagnosis, control, optimization, and applications to computer and software systems. He co-authored, with C. Cassandras, the textbook Introduction to Discrete Event Systems (2nd Edition, Springer, 2008). He has served as Editor-in-Chief of the journal Discrete Event Dynamic Systems: Theory and Applications since 2015.
