Model Predictive Control for Constrained Linear Positive Systems on Graphs
Roland Schurig, David Ohlin, Anders Rantzer +2
Positive systems describing networks with inherently non-negative states and inputs arise naturally in routing, logistics, and compartmental modelling. We consider problems modelle…
Positive Observers Revisited
David Ohlin, Anders Rantzer, Emma Tegling
The paper shows that positive linear systems can be stabilized using positive Luenberger-type observers. This is achieved by structuring the observer as monotonically converging up…
A Minimax Optimal Controller for Positive Systems
Alba Gurpegui, Emma Tegling, Anders Rantzer
We present an explicit solution to the discrete-time Bellman equation for minimax optimal control of positive systems under unconstrained disturbances. The primary contribution of…
Minimax Linear Regulator Problems for Positive Systems
Alba Gurpegui, Mark Jeeninga, Emma Tegling +1
Explicit solutions to optimal control problems are rarely obtainable. Of particular interest are the explicit solutions derived for minimax problems, providing a framework to addre…
Performance bounds for multi-vehicle networks with local integrators
Jonas Hansson, Emma Tegling
In this work, we consider the problem of coordinating a collection of th-order integrator systems. The coordination is achieved through the novel serial-consensus design, which…
Heuristic Search for Linear Positive Systems
David Ohlin, Anders Rantzer, Emma Tegling
This work considers infinite-horizon optimal control of positive linear systems applied to the case of network routing problems. We demonstrate the equivalence between Stochastic S…
Achieving consensus in networks of increasingly stubborn voters
David Ohlin, Fethi Bencherki, Emma Tegling
We study opinion evolution in networks of stubborn agents discussing a sequence of issues, modeled through the so called concatenated Friedkin-Johnsen (FJ) model. It is concatenate…
Closed-loop design for scalable performance of vehicular formations
Jonas Hansson, Emma Tegling
This paper presents a novel control design for vehicular formations, which is an alternative to the conventional second-order consensus protocol. The design is motivated by the clo…

Alba Gurpegui, Emma Tegling, Anders Rantzer
We present a novel class of minimax optimal control problems with positive dynamics, linear objective function and homogeneous constraints. The proposed problem class can be analyz…
Optimal Control of Linear Cost Networks
David Ohlin, Emma Tegling, Anders Rantzer
We present a method for optimal control with respect to a linear cost function for positive linear systems with coupled input constraints. We show that the optimal cost function an…
A closed-loop design for scalable high-order consensus
Jonas Hansson, Emma Tegling
This paper studies the problem of coordinating a group of th-order integrator systems. As for the well-studied conventional consensus problem, we consider linear and distributed…
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…
Scale Fragilities in Localized Consensus Dynamics
Emma Tegling, Bassam Bamieh, Henrik Sandberg
We consider distributed consensus in networks where the agents have integrator dynamics of order two or higher (). We assume all feedback to be localized in the sense that…
Inverse optimal control for angle stabilization in converters-based generation
Taouba Jouini, Anders Rantzer, Emma Tegling
In inverse optimal control, the optimality of a given feedback stabilizing controller is a byproduct of the choice of a meaningful, a posteriori defined, cost functional. This allo…
Grid-forming lambda-omega virtual oscillator control in converter-based power systems
