Fractional-Order PII1/2DD1/2 Control: Theoretical Aspects and Application to a Mechatronic Axis

open access: yesApplied Sciences, 2021
Fractional Calculus is usually applied to control systems by means of the well-known PIλDμ scheme, which adopts integral and derivative components of non-integer orders λ and µ. An alternative approach is to add equally distributed fractional-order terms

The Ordered Distribute Constraint [PDF]

open access: yes2010 22nd IEEE International Conference on Tools with Artificial Intelligence, 2010
In this paper we introduce a new cardinality constraint: Ordered Distribute. Given a set of variables, this constraint limits for each value v the number of times v or any value greater than v is taken. It extends the global cardinality constraint, that constrains only the number of times a value v is taken by a set of variables and does not consider ...

Construction a distributed order smoking model and its nonstandard finite difference discretization

open access: yesAIMS Mathematics, 2022
Smoking is currently one of the most important health problems in the world and increases the risk of developing diseases. For these reasons, it is important to determine the effects of smoking on humans.

Time-fractional telegraph equation of distributed order in higher dimensions

open access: yesCommunications in nonlinear science & numerical simulation, 2021
In this paper, we consider the time-fractional telegraph equation of distributed order in higher spatial dimensions, where the time derivative is in the sense of Hilfer, thus interpolating between the Riemann-Liouville and the Caputo fractional ...

Quasi-Projective Synchronization of Distributed-Order Recurrent Neural Networks

open access: yesFractal and Fractional, 2021
In this paper, the quasi-projective synchronization of distributed-order recurrent neural networks is investigated. Firstly, based on the definition of the distributed-order derivative and metric space theory, two distributed-order differential ...

Stability Analysis of the Nabla Distributed-Order Nonlinear Systems

open access: yesFractal and Fractional, 2022
The stability of the nabla discrete distributed-order nonlinear dynamic systems is investigated in this paper. Firstly, a sufficient condition for the asymptotic stability of the nabla discrete distributed-order nonlinear systems is proposed based on ...

Diffusion with space memory modelled with distributed order space fractional differential equations

open access: yesAnnals of Geophysics, 2003
Distributed order fractional differential equations (Caputo, 1995, 2001; Bagley and Torvik, 2000a,b) were fi rst used in the time domain; they are here considered in the space domain and introduced in the constitutive equation of diffusion.

The Kernel of the Distributed Order Fractional Derivatives with an Application to Complex Materials

open access: yesFractal and Fractional, 2017
The extension of the fractional order derivative to the distributed order fractional derivative (DOFD) is somewhat simple from a formal point of view, but it does not yet have a simple, obvious analytic form that allows its fast numerical calculation ...
