The control of processes with time delays is crucial in process industries such as petrochemical, hydraulic, and manufacturing. It a challenging task for automation engineers, it may affect both phase gain margins. In this case, robust system preferred. This article presents novel controller structure combining computational intelligence (CI) fractional-order control. A PID (FOPID) based on bio...

Abstract Robust watermarking is an effective method and a promising solution for securing protecting the copyright of digital images. Moments moment invariants have become popular tools robust due to their geometric invariance favorable capability image description. Many moments-based schemes been proposed. However, there challenging problem these that should be addressed. One problems improve ...

We consider uncertain fractional-order linear time invariant (FO-LTI) systems with interval coefficients. Our focus is on the robust controllability issue for interval FO-LTI systems in statespace form. We re-visited the controllability problem for the case when there is no interval uncertainty. It turns out that the stability check for FO-LTI systems amounts to checking the conventional intege...

[email protected] University of Bordeaux, IMS Laboratory (CRONE Team), CNRS UMR 5218, 351 Cours de la Libération, 33405 Talence, France Abstract This article addresses the problem of robust pseudo state feedback stabilisation of commensurate fractional order polytopic systems (FOS). In the proposed approach, Linear Matrix Inequalities (LMI) formalism is used to...

approximating the solution of differential equations of fractional order is necessary because fractional differential equations have extensively been used in physics, chemistry as well as engineering fields. in this paper with central difference approximation and newton cots integration formula, we have found approximate solution for a class of boundary value problems of fractional order. three...
