Dual-Loop Voltage–Current Control of a Fractional-Order Buck-Boost Converter Using a Fractional-Order PIλ Controller

open access: yesFractal and Fractional, 2023
Based on the fact that the inductor and capacitor are of a non-integer order by nature, to provide a more accurate theoretical basis for the optimal control of the converter, the fractional-order model of the Buck-Boost converter in the continuous mode ...

Adaptive Control of Milling Forces under Fractional Order Holds [PDF]

open access: yes, 2007
This paper introduces a novel discrete-time modelreference based control of the tool-work-piece interaction force in a milling process. The novelty of the scheme relies on the use of a fractional order hold (FROH) instead of a traditional zero order hold

Analog Realization of Fractional-Order Capacitor and Inductor via the Caputo–Fabrizio Derivative

open access: yesJournal of Advanced Computational Intelligence and Intelligent Informatics, 2021
Capacitors and inductors have been proven to exhibit fractional-order characteristics. Therefore, the establishment of fractional-order models for circuits containing such components is of great significance in practical circuit analysis. This study establishes the impedance models of fractional-order capacitors and inductors based on the Caputo ...

Analysis of discrete time schemes for milling forces control under fractional order holds [PDF]

open access: yes, 2013
In this paper, discrete time model reference control schemes for practical milling using different discretization of the continuous-time plant are presented. First, a basic controller scheme is addressed where a fractional order hold with pre-fixed value

A comprehensive theoretical model for on-chip microring-based photonic fractional differentiators [PDF]

open access: yes, 2015
Microring-based photonic fractional differentiators play an important role in the on-chip all-optical signal processing. Unfortunately, the previous works do not consider the time-reversal and the time delay characteristics of the microring-based ...
