Smooth-Switching Control of Robot-Based Permanent-Magnet Synchronous Motors via Port-Controlled Hamiltonian and Feedback Linearization

open access: yesEnergies, 2020
To solve the contradiction between dynamic performance and steady-state performance of the robot system, a smooth-switching control strategy is proposed.

Simulating Ising-Like Models on Quantum Computer

open access: yesСовременные информационные технологии и IT-образование, 2023
Due to the complexity of lattice models of statistical physics, there is interest in developing new approaches to study them, including those using quantum technologies.

Controlled Lagrangian and Hamiltonian Systems [PDF]

open access: yes, 2002
any control systems are mechanical systems. The unique feature of mechanical systems is the notion of energy, which gives much information on the stability of equilibria.

Hamiltonians for curves [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2002
We examine the equilibrium conditions of a curve in space when a local energy penalty is associated with its extrinsic geometrical state characterized by its curvature and torsion. To do this we tailor the theory of deformations to the Frenet-Serret frame of the curve.

Construction of discrete-time model for port-controlled Hamiltonian systems with applications [PDF]

open access: yes, 2006
The issues of constructing a discrete-time model for Hamiltonian systems are in general different from those for dissipative systems. We propose an algorithm for constructing an approximate discrete-time model, which guarantees Hamiltonian conservation ...

Torus–Connected Cycles: A Simple and Scalable Topology for Interconnection Networks

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2015
Supercomputers are today made up of hundreds of thousands of nodes. The interconnection network is responsible for connecting all these nodes to each other.

The influence of the phase transformation: Fhyd → Fe3O4, occurs during the annealing treatment of Sol-Gel synthesis, on the absorption properties of the final synthesis product: Fe3O4/C hollow-sphere nanoparticles [PDF]

open access: yesScientific Technical Review
In this paper, we perform a theoretical study of the possible improvement of the absorption properties ( ) of the sample consisting of Fe3O4/C hollow sphere nanoparticles, prepared by sol-gel method.

Renormalization of Hamiltonians [PDF]

open access: yesPhysical Review D, 1993
A matrix model of an asymptotically free theory with a bound state is solved using a perturbative similarity renormalization group for hamiltonians. An effective hamiltonian with a small width, calculated including the first three terms in the perturbative expansion, is projected on a small set of effective basis states. The resulting small hamiltonian

An Energy Consistent Discretization of the Nonhydrostatic Equations in Primitive Variables

open access: yesJournal of Advances in Modeling Earth Systems, 2020
We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz staggered vertical discretization. The combination conserves a discrete energy in exact time integration when coupled with a mimetic horizontal discretization ...

Hamiltonian Thermodynamics [PDF]

open access: yesNelineinaya Dinamika, 2020
It is believed that thermodynamic laws are associated with random processes occurring in the system and, therefore, deterministic mechanical systems cannot be described within the framework of the thermodynamic approach. In this paper, we show that thermodynamics (or, more precisely, a thermodynamically-like description) can be constructed even for ...
