Fractional-Order Adaptive Backstepping Control of a Noncommensurate Fractional-Order Ferroresonance System [PDF]

open access: yesMathematical Problems in Engineering, 2018
In this paper, fractional calculus is applied to establish a novel fractional-order ferroresonance model with fractional-order magnetizing inductance and capacitance. Some basic dynamic behaviors of this fractional-order ferroresonance system are investigated.

Hybrid Systems and Control With Fractional Dynamics (II): Control

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 ...

A Fractional-Order On-Line Self Optimizing Control Framework and a Benchmark Control System Accelerated Using Fractional-Order Stochasticity

open access: yesFractal and Fractional, 2022
This paper presents a design and evaluation of a fractional-order self optimizing control (FOSOC) architecture for process control. It is based on a real-time derivative-free optimization layer that adjusts the parameters of a discrete-time fractional ...

CFOA-Based Fractional Order PIλDδ Controller

open access: yesElectronics ETF, 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. This modification can be achieved by using Diamond Transistor (DT) instead of going through complicated IC fabrication process ...

A comparative study of fractional order PIλ /PIλ Dμ tuning rules for stable first order plus time delay processes [PDF]

open access: yes, 2016
Conventional PID tuning methods may not be sufficient to deal with complex processes of modern industry. For better control, fractional order PIλDµ controller was introduced as the generalization of classical PID controller with the help of non-integer ...

Implementing Discrete-time Fractional-order Controllers [PDF]

open access: yesJournal of Advanced Computational Intelligence and Intelligent Informatics, 2001
The theory of fractional calculus goes back to the beginning of the theory of differential calculus but its inherent complexity postponed the application of the associated concepts. In the last decade the progress in the areas of chaos and fractals revealed subtle relationships with the fractional calculus leading to an increasing interest in the ...
