Well-posedness and Stability for Interconnection Structures of Port-Hamiltonian Type

open access: yes, 2019
We consider networks of infinite-dimensional port-Hamiltonian systems $\mathfrak{S}_i$ on one-dimensional spatial domains. These subsystems of port-Hamiltonian type are interconnected via boundary control and observation and are allowed to be of distinct

Optimal fluctuations and the control of chaos. [PDF]

open access: yes, 2002
The energy-optimal migration of a chaotic oscillator from one attractor to another coexisting attractor is investigated via an analogy between the Hamiltonian theory of fluctuations and Hamiltonian formulation of the control problem.

New results for time reversed symplectic dynamic systems and quadratic functionals

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we examine time scale symplectic (or Hamiltonian) systems and the associated quadratic functionals which contain a forward shift in the time variable.

Submersions, Hamiltonian systems and optimal solutions to the rolling manifolds problem

open access: yes, 2016
Given a submersion $\pi:Q \to M$ with an Ehresmann connection $\mathcal{H}$, we describe how to solve Hamiltonian systems on $M$ by lifting our problem to $Q$.

Phase-Space Modeling and Control of Robots in the Screw Theory Framework Using Geometric Algebra

open access: yesMathematics, 2023
The following paper talks about the dynamic modeling and control of robot manipulators using Hamilton’s equations in the screw theory framework. The difference between the proposed work with diverse methods in the literature is the ease of obtaining the ...

The Port-Hamiltonian Formulation of Thermodynamics—A New Perspective

open access: yesEnergies
This paper proposes a change in the traditional epistemological paradigm and a look at classical thermodynamics from the point of view of control theory, with the aim of discovering energy state variables. The paper proposes a transition from “causality”

Geometric Modeling for Control of Thermodynamic Systems

open access: yesEntropy, 2023
This paper discusses the way that energy and entropy can be regarded as storage functions with respect to supply rates corresponding to the power and thermal ports of the thermodynamic system. Then, this research demonstrates how the factorization of the

A family of virtual contraction based controllers for tracking of flexible‐joints port‐Hamiltonian robots: Theory and experiments [PDF]

open access: yesInternational Journal of Robust and Nonlinear Control, 2020
SummaryIn this work, we present a constructive method to design a family of virtual contraction based controllers that solve the standard trajectory tracking problem of flexible‐joint robots in the port‐Hamiltonian framework. The proposed design method, called virtual contraction based control, combines the concepts of virtual control systems and ...
