Learning port-Hamiltonian Systems—Algorithms
Computational Mathematics and Mathematical Physics, 2023 In this article we study the possibilities of recovering the structure of port-Hamiltonian systems starting from “unlabelled” ordinary differential equations describing mechanical systems. The algorithm we suggest solves the problem in two phases.

Mathematical and Computer Modelling of Dynamical Systems, 2023 A fluid–structure interaction model in a port-Hamiltonian representation is derived for a classical guitar. After discretization, we combine the laws of continuum mechanics for solids and fluids within a unified port-Hamiltonian (pH) modelling approach ...

Time-domain Dynamic State Estimation for Unbalanced Three-phase Power Systems
Journal of Modern Power Systems and Clean Energy, 2023 In this paper, we present a time-domain dynamic state estimation for unbalanced three-phase power systems. The dynamic nature of the estimator stems from an explicit consideration of the electromagnetic dynamics of the network, i.e., the dynamics of the ...

A Rosenbrock framework for tangential interpolation of port-Hamiltonian descriptor systems
Mathematical and Computer Modelling of Dynamical Systems, 2023 We present a new structure-preserving model order reduction (MOR) framework for large-scale port-Hamiltonian descriptor systems (pH-DAEs). Our method exploits the structural properties of the Rosenbrock system matrix for this system class and utilizes ...

Observability for port-Hamiltonian systems [PDF]
2021 European Control Conference (ECC), 2021 The class of port-Hamiltonian systems incorporates many physical models, such as mechanical systems in the finite-dimensional case and wave and beam equations in the infinite-dimensional case. In this paper we study a subclass of linear first order port-Hamiltonian systems.

Optimal Robustness of Port-Hamiltonian Systems [PDF]
SIAM Journal on Matrix Analysis and Applications, 2020 We construct optimally robust port-Hamiltonian realizations of a given rational transfer function that represents a passive system. We show that the realization with a maximal passivity radius is a normalized port-Hamiltonian one. Its computation is linked to a particular solution of a linear matrix inequality that defines passivity of the transfer ...
