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…
A Structured Optimal Controller for Irrigation Networks
Martin Heyden, Richard Pates, Anders Rantzer
In this paper, we apply an optimal LQ controller, which has an inherent structure that allows for a distributed implementation, to an irrigation network. The network consists of a…
The Scaled Relative Graph of a Linear Operator
Richard Pates
The scaled relative graph (SRG) of an operator is a subset of the complex plane. It captures several salient features of an operator, such as contractiveness, and can be used to re…
On the Optimal Control of Relaxation Systems
Richard Pates, Carolina Bergeling, Anders Rantzer
The relaxation systems are an important subclass of the passive systems that arise naturally in applications. We exploit the fact that they have highly structured state-space reali…
On Closed-form H-infinity Optimal Control and Large-scale Systems
Carolina Bergeling, Richard Pates, Anders Rantzer
We address a class of systems for which the solution to an H-infinity optimal control problem can be given on a very simple closed form. In fact, both the control law and optimal p…
Sensitivity Function Trade-offs for Networks with a String Topology
Richard Pates, Kaoru Yamamoto
We present two sensitivity function trade-offs that apply to a class of networks with a string topology. In particular we show that a lower bound on the H-infinity norm and a Bode…
