Second-order bulk-surface splitting for the wave equation with kinetic boundary conditions
R. Altmann, R. Morandin
This paper is devoted to the numerical analysis of a second-order bulk--surface splitting scheme for the semi-linear wave equation with kinetic boundary conditions. The constructio…
Discrete gradient methods for port-Hamiltonian differential-algebraic equations
Philipp L. Kinon, Riccardo Morandin, Philipp Schulze
Discrete gradient methods are a powerful tool for the time discretization of dynamical systems, since they are structure-preserving regardless of the form of the total energy. In t…
Relationship between dissipativity concepts for linear time-varying port-Hamiltonian systems
Karim Cherifi, Hannes Gernandt, Dorothea Hinsen +2
The relationship between different dissipativity concepts for linear time-varying systems is studied, in particular between port-Hamiltonian systems, passive systems, and systems w…
Dissipative energy functionals of passive linear time-varying systems
Riccardo Morandin, Dorothea Hinsen
The concept of dissipativity plays a crucial role in the analysis of control systems. Dissipative energy functionals, also known as Hamiltonians, storage functions, or Lyapunov fun…
Port-Hamiltonian Dynamic Mode Decomposition
Riccardo Morandin, Jonas Nicodemus, Benjamin Unger
We present a novel physics-informed system identification method to construct a passive linear time-invariant system. In more detail, for a given quadratic energy functional, measu…
Error bounds for port-Hamiltonian model and controller reduction based on system balancing
Tobias Breiten, Riccardo Morandin, Philipp Schulze
We study linear quadratic Gaussian (LQG) control design for linear port-Hamiltonian systems. To this end, we exploit the freedom in choosing the weighting matrices and propose a sp…
Structure-preserving discretization for port-Hamiltonian descriptor systems
Volker Mehrmann, Riccardo Morandin
We extend the modeling framework of port-Hamiltonian descriptor systems to include under- and over-determined systems and arbitrary differentiable Hamiltonian functions. This struc…
Qualitative Stability and Synchronicity Analysis of Power Network Models in Port-Hamiltonian Form
Volker Mehrmann, Riccardo Morandin, Simona Olmi +1
In view of highly decentralized and diversified power generation concepts, in particular with renewable energies such as wind and solar power, the analysis and control of the stabi…
