Kernel-based Koopman approximants for control: Flexible sampling, error analysis, and stability
Lea Bold, Friedrich M. Philipp, Manuel Schaller +1
Data-driven techniques for analysis, modeling, and control of complex dynamical systems are on the uptake. Koopman theory provides the theoretical foundation for the popular kernel…
Nonlinear controlled port-Hamiltonian systems: Existence of (optimal) solutions
Willem Esterhuizen, Bernhard Maschke, Till Preuster +2
We investigate the existence of solutions of reversible and irreversible port-Hamilto\-nian systems. To this end, we utilize the associated exergy, a function that is composed of t…
A continuous-time fundamental lemma and its application in data-driven optimal control
Philipp Schmitz, Timm Faulwasser, Paolo Rapisarda +1
Data-driven control of discrete-time and continuous-time systems is of tremendous research interest. In this paper, we explore data-driven optimal control of continuous-time linear…
Distributed Optimization for Energy Grids: A Tutorial on ADMM and ALADIN
Lukas Lanza, Timm Faulwasser, Karl Worthmann
The ongoing transition towards energy and power systems dominated by a large number of renewable power injections to the distribution grid poses substantial challenges for system o…
Towards Efficient Aggregation of Storage Flexibilities in Power Grids
Emrah Öztürk, Kevin Kaspar, Timm Faulwasser +3
The increasing penetration of volatile renewables combined with increasing demands poses a challenge to modern power grids. Furthermore, distributed energy resources and flexible d…
Perturbations in PDE-constrained optimal control decay exponentially in space
Simone Göttlich, Manuel Schaller, Karl Worthmann
For linear-quadratic optimal control problems (OCPs) governed by elliptic and parabolic partial differential equations (PDEs), we investigate the impact of perturbations on optimal…
