Research on rehabilitation robot control based on port-Hamiltonian systems and fatigue dissipation port compensation [PDF]
Frontiers in Bioengineering and BiotechnologyIntroductionUpper-limb rehabilitation robots have been demonstrated to effectively promote motor recovery in stroke patients. However, in active training modes, control instability may be induced by the nonlinear and time-varying characteristics of ...

Discrete port-Hamiltonian systems: mixed interconnections [PDF]
Proceedings of the 44th IEEE Conference on Decision and Control, 2005 Either from a control theoretic viewpoint or from an analysis viewpoint it is necessary to convert smooth systems to discrete systems, which can then be implemented on computers for numerical simulations.

Geometry of Thermodynamic Processes [PDF]
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.

On interconnections of infinite-dimensional port-Hamiltonian systems [PDF]
, 2004 Network modeling of complex physical systems leads to a class of nonlinear systems called port-Hamiltonian systems, which are defined with respect to a Dirac structure (a geometric structure which formalizes the power-conserving interconnection structure

Riesz Bases of Port-Hamiltonian Systems [PDF]
SIAM Journal on Control and Optimization, 2021 The location of the spectrum and the Riesz basis property of well-posed homogeneous infinite-dimensional linear port-Hamiltonian systems on a 1D spatial domain are studied. It is shown that the Riesz basis property is equivalent to the fact that system operator generates a strongly continuous group.

Stochastic Port-Hamiltonian Systems
Journal of Nonlinear Science, 2022 AbstractIn the present work we formally extend the theory of port-Hamiltonian systems to include random perturbations. In particular, suitably choosing the space of flow and effort variables we will show how several elements coming from possibly different physical domains can be interconnected in order to describe a dynamic system perturbed by general ...

Modeling and Analysis of a Three-Terminal-Memristor-Based Conservative Chaotic System
Entropy, 2021 In this paper, a three-terminal memristor is constructed and studied through changing dual-port output instead of one-port. A new conservative memristor-based chaotic system is built by embedding this three-terminal memristor into a newly proposed four ...

A port-Hamiltonian formulation of coupled heat transfer
Mathematical and Computer Modelling of Dynamical Systems, 2022 Heat transfer and cooling solutions play an important role in the design of gas turbine blades. However, the underlying mathematical coupling structures have not been thoroughly investigated. In this work, the port-Hamiltonian formalism is applied to the
