Generalized port-Hamiltonian DAE systems [PDF]
Systems & Control Letters, 2018 Motivated by recent work in this area we expand on a generalization of port-Hamiltonian systems that is obtained by replacing the Hamiltonian function representing energy storage by a general Lagrangian subspace. This leads to a new class of algebraic constraints in physical systems modeling, and to an interesting class of DAE systems.

Irreversible port-Hamiltonian systems : a general formulation of irreversible processes with application to the CSTR. [PDF]
Chemical Engineering Science, 2013 International audienceIn this paper we suggest a class of quasi-port Hamiltonian systems called Irreversible port Hamiltonian Systems, that expresses simultaneously the first and second principle of thermodynamics as a structural property.

Weak Form of Stokes-Dirac Structures and Geometric Discretization of Port-Hamiltonian Systems
Journal of Computational Physics, 2018 We present the mixed Galerkin discretization of distributed parameter port-Hamiltonian systems. On the prototypical example of hyperbolic systems of two conservation laws in arbitrary spatial dimension, we derive the main contributions: (i) A weak ...

Frontiers in Applied Mathematics and Statistics, 2023 We discuss structure-preserving model order reduction for port-Hamiltonian systems based on a nonlinear approximation ansatz which is linear with respect to a part of the state variables of the reduced-order model.

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 ...

Exergetic port-Hamiltonian systems: modelling basics [PDF]
Mathematical and Computer Modelling of Dynamical Systems, 2021 Port-Hamiltonian systems theory provides a structured approach to modelling, optimization and control of multiphysical systems. Yet, its relationship to thermodynamics seems to be unclear. The Hamiltonian is traditionally thought of as energy, although its meaning is exergy. This insight yields benefits: 1. Links to the GENERIC structure are identified,

Port-Hamiltonian Systems on Graphs [PDF]
SIAM Journal on Control and Optimization, 2013 In this paper we present a unifying geometric and compositional framework for modeling complex physical network dynamics as port-Hamiltonian systems on open graphs. Basic idea is to associate with the incidence matrix of the graph a Dirac structure relating the flow and effort variables associated to the edges, internal vertices, as well as boundary ...
