Synchronization in Networks of Diffusively Coupled Nonlinear Systems: Robustness Against Time-Delays
Carlos Murguia, Henk Nijmeijer, Justin Ruths
In this manuscript, we study the problem of robust synchronization in networks of diffusively time-delayed coupled nonlinear systems. In particular, we prove that, under some mild…
On Reachable Sets of Hidden CPS Sensor Attacks
Carlos Murguia, Justin Ruths
For given system dynamics, observer structure, and observer-based fault/attack detection procedure, we provide mathematical tools -- in terms of Linear Matrix Inequalities (LMIs) -…
Characterization of Model-Based Detectors for CPS Sensor Faults/Attacks
Carlos Murguia, Justin Ruths
A vector-valued model-based cumulative sum (CUSUM) procedure is proposed for identifying faulty/falsified sensor measurements. First, given the system dynamics, we derive tools for…
A Comparison of Stealthy Sensor Attacks on Control Systems
Navid Hashemi, Carlos Murguia, Justin Ruths
As more attention is paid to security in the context of control systems and as attacks occur to real control systems throughout the world, it has become clear that some of the most…
Constraining Attacker Capabilities Through Actuator Saturation
Sahand Hadizadeh Kafash, Jairo Giraldo, Carlos Murguia +2
For LTI control systems, we provide mathematical tools - in terms of Linear Matrix Inequalities - for computing outer ellipsoidal bounds on the reachable sets that attacks can indu…
Tuning Windowed Chi-Squared Detectors for Sensor Attacks
Tunga R, Carlos Murguia, Justin Ruths
A model-based windowed chi-squared procedure is proposed for identifying falsified sensor measurements. We employ the widely-used static chi-squared and the dynamic cumulative sum…
