Nonlinear Dynamical Unbalanced Optimal Transport: Relaxation and Duality
Dongjun Wu, Anders Rantzer
In this paper, we introduce a generalized dynamical unbalanced optimal transport framework by incorporating limited control input and mass dissipation, addressing limitations in co…
A Cone-preserving Solution to a Nonsymmetric Riccati Equation
Emil Vladu, Anders Rantzer
In this paper, we provide the following simple equivalent condition for a nonsymmetric Algebraic Riccati Equation to admit a stabilizing cone-preserving solution: an associated coe…
On PI-control in Capacity-Limited Networks
Felix Agner, Anders Rantzer
This paper concerns control of a class of systems where multiple dynamically stable agents share a nonlinear and bounded control-interconnection. The agents are subject to a distur…
Duality-based Dynamical Optimal Transport of Discrete Time Systems
Dongjun Wu, Anders Rantzer
We study dynamical optimal transport of discrete time systems (dDOT) with Lagrangian cost. The problem is approached by combining optimal control and Kantorovich duality theory. Ba…
Hydraulic Parameter Estimation for District Heating Based on Laboratory Experiments
Felix Agner, Christian Møller Jensen, Anders Rantzer +2
In this paper we consider calibration of hydraulic models for district heating systems based on operational data. We extend previous theoretical work on the topic to handle real-wo…
A data-based comparison of methods for reducing the peak volume flow rate in a district heating system
Felix Agner, Ulrich Trabert, Anders Rantzer +1
This work concerns reduction of the peak flow rate of a district heating grid, a key system property which is bounded by pipe dimensions and pumping capacity. The peak flow rate co…
Optimal Mass Transport of Nonlinear Systems under Input and Density Constraints
Dongjun Wu, Anders Rantzer
We investigate optimal mass transport problem of affine-nonlinear dynamical systems with input and density constraints. Three algorithms are proposed to tackle this problem, includ…
Nonasymptotic Regret Analysis of Adaptive Linear Quadratic Control with Model Misspecification
Bruce D. Lee, Anders Rantzer, Nikolai Matni
The strategy of pre-training a large model on a diverse dataset, then fine-tuning for a particular application has yielded impressive results in computer vision, natural language p…
Distributed Adaptive Control for Uncertain Networks
Venkatraman Renganathan, Anders Rantzer, Olle Kjellqvist
Control of network systems with uncertain local dynamics has remained an open problem for a long time. In this paper, a distributed minimax adaptive control algorithm is proposed f…
Decentralized PI-control and Anti-windup in Resource Sharing Networks
Felix Agner, Jonas Hansson, Pauline Kergus +3
We consider control of multiple stable first-order \review{agents} which have a control coupling described by an M-matrix. These agents are subject to incremental sector-bounded \r…
