Controlling fractional difference equations using feedback
One of the most popular methods of controlling dynamical systems is feedback. It can be used without acquiring detailed knowledge of the underlying system. In this work, we study the stability of fractional-order linear difference equations under feedback. The stability results are derived for an arbitrary feedback time $τ$. We study the cases of $τ=1$

In this paper, we solve two-dimensional modified anomalous fractional sub-diffusion equation using modified implicit finite difference approximation. The stability and convergence of the proposed scheme are analyzed by the Fourier series method.

This paper presents integer and linear time-invariant fractional order (FO) models of a closed-loop electric individual-wheel drive implemented on an autonomous platform. Two discrete-time FO models are tested: non-commensurate and commensurate.

A Hilbert Space Approach to Fractional Difference Equations [PDF]
We formulate fractional difference equations of Riemann-Liouville and Caputo type in a functional analytical framework. Main results are existence of solutions on Hilbert space-valued weighted sequence spaces and a condition for stability of linear fractional difference equations.

Modeling with fractional difference equations
A fractional sum of a function \(f\) is introduced as \[ \Delta _{a}^{-\alpha}f(t)=\frac{1}{\Gamma (\alpha )}\sum_{s=a}^{t-\alpha }(t-s-1)^{(\alpha -1)}f(s), \] where \(a\in R,\) \(\alpha >0\), \(x^{(\alpha )}=\Gamma (x+1)/\Gamma (x-\alpha +1),\) \(f\) is defined for \(s=a\;(\text{mod }1),\) and \(\Delta _{a}^{-\alpha }f\) is defined for \(t=a+\alpha \;
