Robust Fault-Tolerant Control for Stochastic Port-Hamiltonian Systems against Actuator Faults
Mathematics, 2022 Exploiting the stochastic Hamiltonian structure, this paper investigates the robust fault-tolerant control (FTC) for stochastic port-Hamiltonian systems (SPHSs) with actuator faults.

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 ...

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 ...

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.

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 ...

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.
