Control of finite-dimensional port-Hamiltonian systems

open access: yes, 2009
We discuss in this chapter a number of approaches to exploit the modelstructure of port-Hamiltonian systems for control purposes. Actually, the formulationof physical control systems as port-Hamiltonian systems may lead in somecases to a re-thinking of ...

Bounded Frequency Lattices in Coupled Lithium Niobate Ring Cavities

open access: yesLaser &Photonics Reviews, EarlyView.
We leverage coupled asymmetric ring resonators in realizing bounded tight‐binding frequency lattices and demonstrate their discrete band structures on an integrated device. Suppression of long‐range coupling with a single auxiliary cavity is demonstrated by combining mode splitting and coupled waveguide dispersion effects.

Interconnection of port-Hamiltonian systems and composition of Dirac structures [PDF]

open access: yes, 2006
Port-based network modeling of physical systems leads to a model class of nonlinear systems known as port-Hamiltonian systems. Port-Hamiltonian systems are defined with respect to a geometric structure on the state space, called a Dirac structure ...

Geometry of Thermodynamic Processes

open access: yesEntropy, 2018
Since the 1970s, contact geometry has been recognized as an appropriate framework for the geometric formulation of thermodynamic systems, and in particular their state properties.

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Energy-based Hamiltonian approach in H∞ controller design for n-degree of freedom mechanical systems

open access: yesSystems Science & Control Engineering, 2019
This paper studies the energy-based approach for ${H_\infty } $ controller design of $n $-degree of freedom mechanical systems. In this approach, the Hamiltonian function, which is the sum of kinetic and potential energies of the system, is considered as

Nonlinear Disturbance Observer-Based Control for a Class of Port-Controlled Hamiltonian Disturbed Systems

open access: yesIEEE Access, 2018
In this paper, a composite control scheme is presented to asymptotically stabilize a class of port-controlled Hamiltonian systems under nonvanishing disturbances.

Passive modelling of the electrodynamic loudspeaker: from the Thiele–Small model to nonlinear port-Hamiltonian systems

open access: yesActa Acustica, 2020
The electrodynamic loudspeaker couples mechanical, magnetic, electric and thermodynamic phenomena. The Thiele/Small (TS) model provides a low frequency approximation, combining passive linear (multiphysical or electric-equivalent) components.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

A class of port-controlled Hamiltonian systems [PDF]

open access: yes, 2005
In this paper, we examine a particular class of port-controlled Hamiltonian systems for which the equations can be written in a form that is very similar to the equations of a linear passive system.
