Fractional Order Impedance Control

open access: yesIEEE Access, 2020
This paper proposes a novel fractional order impedance control. In traditional impedance control model, the orders of inertia, damping, and stiffness are integers and the contact force can be reduced effectively to some extent in robots and manipulators.

Fractional order elliptic problems with inhomogeneous Dirichlet boundary conditions [PDF]

open access: yes, 2020
Fractional-order elliptic problems are investigated in case of inhomogeneous Dirichlet boundary data. The boundary integral form is proposed as a suitable mathematical model.

Fractional Order Compartment Models

open access: yesSIAM Journal on Applied Mathematics, 2017
This paper is an interesting application of fractional order systems. Compartment models are well known and well studied in the literature. To describe the time evolution of a system undergoing reactions between populations in different compartments, often compartment models are used. These are set of differential equations coupled together.

The potential of fractional order distributed MPC applied to steam/water loop in large scale ships [PDF]

open access: yes, 2020
The steam/water loop is a crucial part of a steam power plant. However, satisfying control performance is difficult to obtain due to the frequent disturbance and load fluctuation.

Fractional-Order Traveling Wave Approximations for a Fractional-Order Neural Field Model

open access: yesFrontiers in Computational Neuroscience, 2022
In this work, we establish a fractional-order neural field mathematical model with Caputo's fractional derivative temporal order α considering 0 < α < 2, to analyze the effect of fractional-order on cortical wave features observed preceding seizure

Fractional-Order LQR and State Observer for a Fractional-Order Vibratory System

open access: yesApplied Sciences, 2021
The present study uses linear quadratic regulator (LQR) theory to control a vibratory system modeled by a fractional-order differential equation. First, as an example of such a vibratory system, a viscoelastically damped structure is selected.

Fractional-Order Euler-Lagrange Equation for Fractional-Order Variational Method: A Necessary Condition for Fractional-Order Fixed Boundary Optimization Problems in Signal Processing and Image Processing

open access: yesIEEE Access, 2016
This paper discusses a novel conceptual formulation of the fractional-order Euler-Lagrange equation for the fractional-order variational method, which is based on the fractional-order extremum method. In particular, the reverse incremental optimal search

Continuous dependence for NLS in fractional order spaces [PDF]

open access: yes, 2010
We consider the Cauchy problem for the nonlinear Schr\"odinger equation $iu_t+ \Delta u+ \lambda |u|^\alpha u=0$ in $\R^N $, in the $H^s$-subcritical and critical cases ...
