“…This also has similar structure like that of Elshurafa et al (2013), the only difference is instead of graphenepolymer composite, here the electrolyte is Pt-polymer composite. And the platinum (Pt) absorption time (in the membrane, during fabrication) determines the a of the FOE.…”

Fractional order (FO) element (FOE) is the building block for realization of FO systems, an important research domain. However, the realization of FO system is still a challenge. Till date, no FOE or fractor is available in the market. However, many researchers have developed various types of FOE, multi-component and single component, over past 50 years or more. This paper reviews some significant research work, along with their success and limitations, in the field of FOE realization. Also, it discusses the chronological development and a brief comparative study to present an overall idea on current stage of FOE research to the readers.

“…''Realization of FOE''). This concept is realized in a more structured way in the graphene-polymer composite based FOE, developed by Elshurafa et al in (2013). In this work, di-electric of conventional parallel plate capacitor is replaced by a polymer composite, percolated with reduced graphene oxide.…”

“…The association between non-continuous materials and Fractional Order Systems [1][2][3][4] is an actual research issue involving investigation at the micro-and macroscopic scale [5,6]. This research follows the recent decades' stream, according to which an increasing interest has arisen for non-continuous, heterogeneous, and composite materials.…”

Abstract:The paper presents a fractional order model of a heating process and a comparison of fractional and standard PI controllers in its closed loop system. Preliminarily, an enhanced fractional order model for the heating process on non-continuous materials has been identified through a fitting algorithm on experimental data. Experimentation has been carried out on a finite length beam filled with three non-continuous materials (air, styrofoam, metal buckshots) in order to identify a model in the frequency domain and to obtain a relationship between the fractional order of the heating process and the different materials' properties. A comparison between the experimental model and the theoretical one has been performed, proving a significant enhancement of the fitting performances. Moreover the obtained modelling results confirm the fractional nature of the heating processes when diffusion occurs in non-continuous composite materials, and they show how the model's fractional order can be used as a characteristic parameter for non-continuous materials with different composition and structure. Finally, three different kinds of controllers have been applied and compared in order to keep constant the beam temperature constant at a fixed length.

“…In other words, the actual inductors and capacitors are fractional-order in nature [13][14][15][16]. More specifically, the fractional-order capacitors are obtained by different designing ways [17][18][19][20]. Also, Machado and Galhano [21] pointed that the discretional fractional orders of inductors could be designed based on the skin effect.…”

-This paper introduces the fundamentals of the conventional LC low-pass filter circuit in the fractional domain. First, we study the new fundamentals of fractional-order LC low-pass filter circuit including the pure real angular frequency, the pure imaginary angular frequency and the short circuit angular frequency. Moreover, sensitivity analysis of the impedance characteristics and phase characteristics of the LC low-pass filter circuit with respect to the system variables is studied in detail, which shows the greater flexibility of the fractional-order filter circuit in designs. Furthermore, from the filtering property perspective, we systematically investigate the effects of the system variables (LC, frequency f and fractional orders) on the amplitude-frequency characteristics and phase-frequency characteristics. In addition, the detailed analyses of the cut-off frequency and filter factor are presented. Numerical experimental results are presented to verify the theoretical results introduced in this paper.
