Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International 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 ...

Memristive port-Hamiltonian Systems [PDF]

, 2010
The port-Hamiltonian modelling framework is extended to a class of systems containing memristive elements and phenomena. First, the concept of memristance is generalised to the same generic level as the port-Hamiltonian framework.

Geometry of Thermodynamic Processes

Entropy, 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.

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

Journal of Field Robotics, EarlyView.
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

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

, 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 ...

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

IEEE 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

Acta 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.

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 812-821, August 2026.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Control of Port-Hamiltonian Systems [PDF]

, 2016
In this chapter, we will exploit the port-Hamiltonian structure for control, going beyond passivity. We will mainly concentrate on the problem of set-point stabilization.

Port-Hamiltonian systems: an introductory survey [PDF]

, 2006
The theory of port-Hamiltonian systems provides a framework for the geometric description of network models of physical systems. It turns out that port-based network models of physical systems immediately lend themselves to a Hamiltonian description ...
