Input-Output Pseudospectral Bounds for Transient Analysis of Networked and High-Order Systems
Jonas Hansson, Emma Tegling
Motivated by a need to characterize transient behaviors in large network systems in terms of relevant signal norms and worst-case input scenarios, we propose a novel approach based…
Limitations of time-delayed case isolation in heterogeneous SIR models
Jonas Hansson, Alain Govaert, Richard Pates +2
Case isolation, that is, detection and isolation of infected individuals in order to prevent spread, is a strategy to curb infectious disease epidemics. Here, we study the efficien…
Grid-forming lambda-omega virtual oscillator control in converter-based power systems
Taouba Jouini, Emma Tegling, Zhiyong Sun
Inspired by the kinetics of wave phenomena in reaction-diffusion models of biological systems, we propose a novel grid-forming control strategy for control of three-phase DC/AC con…
Localized high-order consensus destabilizes large-scale networks
Emma Tegling, Bassam Bamieh, Henrik Sandberg
We study the problem of distributed consensus in networks where the local agents have high-order () integrator dynamics, and where all feedback is localized in that each ag…
Scalability and Fragility in Bounded-Degree Consensus Networks
Emma Tegling, Richard H. Middleton, Maria M. Seron
We investigate the performance of linear consensus algorithms subject to a scaling of the underlying network size. Specifically, we model networked systems with ord…
Noise-Induced Limitations to the Scalability of Distributed Integral Control
Emma Tegling, Henrik Sandberg
We study performance limitations of distributed feedback control in large-scale networked dynamical systems. Specifically, we address the question of how the performance of distrib…
