Port-Hamiltonian fluid–structure interaction modelling and structure-preserving model order reduction of a classical guitar

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 ...

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.

A Reversible Hydropump–Turbine System

Applied Sciences, 2022
Water-pumped storage systems have become an ideal alternative to regulate the intermittent power delivered by renewable energy sources. For small-scale operations, a type of centrifugal pump coupled to asynchronous machines represents an adequate ...

On Energy Conversion in Port-Hamiltonian Systems [PDF]

2021 60th IEEE Conference on Decision and Control (CDC), 2021
We study port-Hamiltonian systems with two external ports, and the strategies and limitations for conversion of energy from one port into the other. It turns out that, apart from the cyclo-passivity of port-Hamiltonian systems, this is related to the internal connection structure of port-Hamiltonian systems. A source of motivation for energy conversion

A Finite Dimensional Approximation of the shallow water Equations: The port-Hamiltonian Approach [PDF]

, 2006
We look into the problem of approximating a distributed parameter port-Hamiltonian system which is represented by a non-constant Stokes-Dirac structure.

Discrete exterior geometry approach to structure-preserving discretization of distributed-parameter port-Hamiltonian systems [PDF]

, 2011
This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce a simplicial Dirac structure as a discrete analogue

On Factorization, Interconnection and Reduction of Collocated Port-Hamiltonian Systems [PDF]

, 2004
Based on a geometric interpretation of nonlinear balanced reduction some implications of this approach are analyzed in the case of collocated port-Hamiltonian systems which have a certain balance in its structure.
