Title: Cyber-Attack Resilient and Communication-Aware Networked Control Systems
Abstract: The term Networked Control System (NCS) refers to a time-critical and safety-critical control process where the control feedback loop is closed via a real-time communication network. The use of a shared communication network provides multiple advantages from a design and operational perspective but can also introduce several challenges such as the overutilization of common resources and the loss of real-time data integrity and availability due to cyber-attacks. Failure to protect the NCS against any of these control and security challenges can lead to catastrophic consequences for the physical process. In the first part of this talk, we will present control tools to detect the launching of replay attacks to multiple sensors and how to safely recover from an attack with minimum performance degradation. We will discuss a cross-level anomaly detector that monitors information of inter-connected processes as well as the power consumption of integrated circuits to determine if a suspected sensor is operating abnormally and determine the best course of action to safely regulate the process. The second part of the talk will focus on the effective use of communication and computing resources within a NCS using the notion of minimum attention control. We present sufficient conditions that guarantee the preservation of convergence, safety, and observability properties despite a reduction in the sampling frequency.
Bio: Erick J. Rodríguez-Seda is an Associate Professor in the Department of Weapons, Robotics, and Control Engineering at United States Naval Academy. He received the B.S. degree in electrical engineering from the University of Puerto Rico, Mayagüez, in 2004 and the M.S. and Ph.D. degrees in electrical and computer engineering from the University of Illinois, Urbana-Champaign, in 2007 and 2011, respectively. From 2011 to 2013 he was a Postdoctoral Research Associate at the University of Texas at Dallas. His primary research interests are in multi-agent systems, collision avoidance, and networked control systems.
