Resilient Distributed Control for Uncertain Nonlinear Interconnected Systems under Network Anomaly
Youqing Wang, Ying Li, Thomas Parisini +1
We address a distributed adaptive control methodology for nonlinear interconnected systems possibly affected by network anomalies. In the framework of adaptive approximation, the d…
Stability, Linear Convergence, and Robustness of the Wang-Elia Algorithm for Distributed Consensus Optimization
Michelangelo Bin, Ivano Notarnicola, Thomas Parisini
We revisit an algorithm for distributed consensus optimization proposed in 2010 by J. Wang and N. Elia. By means of a Lyapunov-based analysis, we prove input-to-state stability of…
Cyber-Physical Risk Assessment for False Data Injection Attacks Considering Moving Target Defences
Martin Higgins, Wangkun Xu, Fei Teng +1
In this paper, we examine the factors that influence the success of false data injection (FDI) attacks in the context of both cyber and physical styles of reinforcement. Many works…
State Estimation Using a Network of Distributed Observers With Unknown Inputs
Guitao Yang, Angelo Barboni, Hamed Rezaee +1
State estimation for a class of linear time-invariant systems with distributed output measurements (distributed sensors) and unknown inputs is addressed in this paper. The objectiv…
Traffic Control in a Mixed Autonomy Scenario at Urban Intersections: An Optimization-based Framework
Arnob Ghosh, Thomas Parisini
We consider an intersection zone where autonomous vehicles (AVs) and human-driven vehicles (HDVs) can be present. As a new vehicle arrives, the traffic controller needs to decide a…
On node ranking in graphs
Ekaterina Dudkina, Michelangelo Bin, Jane Breen +9
The ranking of nodes in a network according to their ``importance'' is a classic problem that has attracted the interest of different scientific communities in the last decades. Th…
Control of a Mixed Autonomy Signalised Urban Intersection: An Action-Delayed Reinforcement Learning Approach
Erica Salvato, Arnob Ghosh, Gianfranco Fenu +1
We consider a mixed autonomy scenario where the traffic intersection controller decides whether the traffic light will be green or red at each lane for multiple traffic-light block…
A Distributed Methodology for Approximate Uniform Global Minimum Sharing
Michelangelo Bin, Thomas Parisini
The paper deals with the distributed minimum sharing problem: a set of decision-makers compute the minimum of some local quantities of interest in a distributed and decentralized w…
Kemeny-based testing for COVID-19
Serife Yilmaz, Ekaterina Dudkina, Michelangelo Bin +6
Testing, tracking and tracing abilities have been identified as pivotal in helping countries to safely reopen activities after the first wave of the COVID-19 virus. Contact tracing…
Towards Distributed Accommodation of Covert Attacks in Interconnected Systems
Angelo Barboni, Thomas Parisini
The problem of mitigating maliciously injected signals in interconnected systems is dealt with in this paper. We consider the class of covert attacks, as they are stealthy and cann…
Stealthy MTD Against Unsupervised Learning-based Blind FDI Attacks in Power Systems
Martin Higgins, Fei Teng, Thomas Parisini
This paper examines how moving target defences (MTD) implemented in power systems can be countered by unsupervised learning-based false data injection (FDI) attack and how MTD can…
Post-Lockdown Abatement of COVID-19 by Fast Periodic Switching
M. Bin, P. Cheung, E. Crisostomi +8
COVID-19 abatement strategies have risks and uncertainties which could lead to repeating waves of infection. We show -- as proof of concept grounded on rigorous mathematical eviden…
Assessing Cyber-Physical Security in Industrial Control Systems
Martín Barrère, Chris Hankin, Demetrios G. Eliades +2
Over the last years, Industrial Control Systems (ICS) have become increasingly exposed to a wide range of cyber-physical threats. Efficient models and techniques able to capture th…
MaxSAT Evaluation 2019 -- Benchmark: Identifying Security-Critical Cyber-Physical Components in Weighted AND/OR Graphs
Martín Barrère, Chris Hankin, Nicolas Nicolau +2
This paper presents a MaxSAT benchmark focused on identifying critical nodes in AND/OR graphs. We use AND/OR graphs to model Industrial Control Systems (ICS) as they are able to se…
Identifying Security-Critical Cyber-Physical Components in Industrial Control Systems
Martín Barrère, Chris Hankin, Nicolas Nicolau +2
In recent years, Industrial Control Systems (ICS) have become an appealing target for cyber attacks, having massive destructive consequences. Security metrics are therefore essenti…
Distributed watermarking for secure control of microgrids under replay attacks
Alexander J. Gallo, Mustafa S. Turan, Francesca Boem +2
The problem of replay attacks in the communication network between Distributed Generation Units (DGUs) of a DC microgrid is examined. The DGUs are regulated through a hierarchical…
A Convex Optimization Approach for Backstepping PDE Design: Volterra and Fredholm Operators
Pedro Ascencio, Alessandro Astolfi, Thomas Parisini
Backstepping design for boundary linear PDE is formulated as a convex optimization problem. Some classes of parabolic PDEs and a first-order hyperbolic PDE are studied, with partic…
