An Unknown Input Multi-Observer Approach for Estimation, Attack Isolation, and Control of LTI Systems under Actuator Attacks
Tianci Yang, Carlos Murguia, Margreta Kuijper +1
We address the problem of state estimation, attack isolation, and control for discrete-time Linear Time Invariant (LTI) systems under (potentially unbounded) actuator false data in…
Closeness of Solutions for Singularly Perturbed Systems via Averaging
Mohammad Deghat, Saeed Ahmadizadeh, Dragan Nesic +1
This paper studies the behavior of singularly perturbed nonlinear differential equations with boundary-layer solutions that do not necessarily converge to an equilibrium. Using the…
On Privacy of Quantized Sensor Measurements through Additive Noise
Carlos Murguia, Iman Shames, Farhad Farokhi +1
We study the problem of maximizing privacy of quantized sensor measurements by adding random variables. In particular, we consider the setting where information about the state of…
Security Metrics of Networked Control Systems under Sensor Attacks (extended preprint)
Carlos Murguia, Iman Shames, Justin Ruths +1
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…
A Multi-Observer Approach for Attack Detection and Isolation of Discrete-Time Nonlinear Systems
Tianci Yang, Carlos Murguia, Margreta Kuijper +1
We address the problem of attack detection and isolation for a class of discrete-time nonlinear systems under (potentially unbounded) sensor attacks and measurement noise. We consi…
A Robust Circle-criterion Observer-based Estimator for Discrete-time Nonlinear Systems in the Presence of Sensor Attacks and Measurement Noise
Tianci Yang, Carlos Murguia, Margreta Kuijper +1
We address the problem of robust state estimation of a class of discrete-time nonlinear systems with positive-slope nonlinearities when the sensors are corrupted by (potentially un…
