This article studies epidemic processes over discrete-time periodic time-varying networks. We focus on the susceptible-infected-susceptible (SIS) model that accounts for a (possibly) mutating virus. We say that an agent is in the disease-free state i

Publikováno v: IFAC-PapersOnLine. 53:797-802

In this paper, we introduce a continuous-time competing virus model with a shared resource. We say that the system is in the healthy state if all the agents are healthy, and the shared resource is not contaminated. If the epidemic remains persistent,

A State Feedback Controller for Mitigation of Continuous-Time Networked SIS Epidemics

Autor: Yuan Wang, Sebin Gracy, César A. Uribe, Hideaki Ishii, Karl Henrik Johansson

The paper considers continuous-time networked susceptible-infected-susceptible (SIS) diseases spreading over a population. Each agent represents a sub-population and has its own healing rate and infection rate; the state of the agent at a time instan

The paper studies input and state observability (ISO) of discrete-time linear time-invariant network systems whose dynamics are affected by unknown inputs. More precisely, we aim at reconstructing the initial state and the sequence of unknown inputs

Actuator Security Index for Structured Systems

Autor: Sebin Gracy, Henrik Sandberg, Jezdimir Milosevic

Publikováno v: ACC

Given a network with a set of vulnerable actuators (and sensors), the security index of an actuator equals the minimum number of sensors and actuators that needs to be compromised so as to conduct a perfectly undetectable attack using the said actuat
