Synchronization of fractional order chaotic systems

open access: yes, 2004
The chaotic dynamics of fractional order systems begin to attract much attentions in recent years. In this brief report, we study the master-slave synchronization of fractional order chaotic systems.

Modeling and Control Research of Fractional-Order Cascaded H-Bridge Multilevel STATCOM

open access: yesFractal and Fractional
This paper introduces fractional-order capacitors and fractional-order inductors into the conventional integer-order cascaded H-bridge multilevel static compensator (ICHM-STATCOM), thereby constructing the main circuit of the fractional-order cascaded H ...

CFOA-Based Fractional Order PIλDδ Controller [PDF]

open access: yesElectronics, 2017
Conventional Current Feedback Operational Amplifier (CFOA) is not current controllable or not electronically controllable. It is thus of interest to add a current mirror into the CFOA in order to make it current controllable.

Non-existence of periodic solutions in fractional-order dynamical systems and a remarkable difference between integer and fractional-order derivatives of periodic functions

open access: yes, 2011
Using the Mellin transform approach, it is shown that, in contrast with integer-order derivatives, the fractional-order derivative of a periodic function cannot be a function with the same period.

Hybrid Systems and Control With Fractional Dynamics (I): Modeling and Analysis

open access: yes, 2014
No mixed research of hybrid and fractional-order systems into a cohesive and multifaceted whole can be found in the literature. This paper focuses on such a synergistic approach of the theories of both branches, which is believed to give additional ...

Electronically Adjustable Emulator of the Fractional-Order Capacitor

open access: yesElektronika ir Elektrotechnika, 2019
This paper presents a design of the controllable emulator of the FOC (Fractional-Order Capacitor) and its application. The circuit is based on 5th-order RC topology (type Foster I), where the passive elements in the topology are replaced by ...

Fractional Order Version of the HJB Equation

open access: yes, 2018
We consider an extension of the well-known Hamilton-Jacobi-Bellman (HJB) equation for fractional order dynamical systems in which a generalized performance index is considered for the related optimal control problem.

FRACTIONAL-ORDER VARIATIONAL DERIVATIVE

open access: yesInternational Journal of Apllied Mathematics, 2016
We consider some possible approaches to the fractional-order generalization of definition of variation (functional) derivative. Some problems of formulation of a fractional-order variational derivative are discussed. To give a consistent definition of the fractional-order variations, we use a fractional generalization of Gateaux differential.

Design of unknown input fractional-order observers for fractional-order systems

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2013
This paper considers a method of designing fractional-order observers for continuous-time linear fractional-order systems with unknown inputs. Conditions for the existence of these observers are given. Sufficient conditions for the asymptotical stability
