Structure-Preserving Discretization and Model Reduction for Energy-Based Models
Robert Altmann, Attila Karsai, Philipp Schulze
We investigate discretization strategies for a recently introduced class of energy-based models. The model class encompasses classical port-Hamiltonian systems, generalized gradien…
A discrete gradient scheme for preserving QSR-dissipativity
Attila Karsai, Philipp Schulze
The notion of dissipative dynamical systems provides a formal description of processes that cannot generate energy internally. For these systems, changes in energy can only occur d…
Energy-based modeling for field-circuit coupling
Robert Altmann, Idoia Cortes Garcia, Elias Paakkunainen +2
This paper presents a generalized energy-based modeling framework extending recent formulations tailored for differential-algebraic equations. The proposed structure, inspired by t…
A novel energy-based modeling framework
R. Altmann, P. Schulze
We introduce an energy-based model, which seems especially suited for constrained systems. The proposed model provides an alternative to the popular port-Hamiltonian framework and…
