Consistent Approximation of Fractional Order Operators [PDF]

open access: yesJournal of Dynamic Systems, Measurement, and Control, 2021
Abstract Fractional order controllers become increasingly popular due to their versatility and superiority in various performances. However, the bottleneck in deploying these tools in practice is related to their analog or numerical implementation.

Some new results on hermite-hadamard-mercer-type inequalities using a general family of fractional integral operators [PDF]

open access: yes, 2021
The aim of this article is to obtain new Hermite-Hadamard-Mercer-type inequalities using Raina's fractional integral operators. We present some distinct and novel fractional Hermite-Hadamard-Mercer-type inequalities for the functions whose absolute value

Diffusive representations for fractional Laplacian: systems theory framework and numerical issues [PDF]

open access: yes, 2009
Bridging the gap between an abstract definition of pseudo-differential operators, such as (-\Delta)^{\gamma} for - 1/2 < \gamma < 1/2, and a concrete way to represent them has proved difficult; deriving stable numerical schemes for such operators is not ...

Analysis of Fractional-Order Nonlinear Dynamic Systems with General Analytic Kernels: Lyapunov Stability and Inequalities

open access: yesMathematics, 2021
In this paper, we study the recently proposed fractional-order operators with general analytic kernels. The kernel of these operators is a locally uniformly convergent power series that can be chosen adequately to obtain a family of fractional operators ...

Spectral Collocation Method for Fractional Differential/Integral Equations with Generalized Fractional Operator

open access: yesInternational Journal of Differential Equations, 2019
Generalized fractional operators are generalization of the Riemann-Liouville and Caputo fractional derivatives, which include Erdélyi-Kober and Hadamard operators as their special cases.

Analysis of the Fractional HIV Model under Proportional Hadamard-Caputo Operators

open access: yesFractal and Fractional, 2023
Modeling human immunodeficiency virus (HIV) via fractional operators has several benefits over the classical integer-order HIV model. The reason is that the fractional HIV model relies not only on the recent status but also on the former conduct of the ...
