Tytuł:: Comparative analysis of dynamic properties of parametric and fractional-order filters
Autorzy:: Jakubowska-Ciszek, Agnieszka
Piwowar, Anna
Powiązania:: https://bibliotekanauki.pl/articles/377115.pdf
Data publikacji:: 2019
Wydawca:: Politechnika Poznańska. Wydawnictwo Politechniki Poznańskiej
Tematy:: parametric filter
fractional-order filter
filter dynamic models
LTV filters
dynamic properties
Opis:: The paper presents transmission models of a parametric filter with non-periodically variable parameters and a fractional-order filter. The responses of these filters on a unit step excitation have been examined as well as the dependence of filters time responses on their parameters. The obtained results have been illustrated by examples.

Tytuł:: Method of identification of equivalent parameters of the fractional-order transformer
Autorzy:: Jakubowska-Ciszek, Agnieszka
Walczak, Janusz
Powiązania:: https://bibliotekanauki.pl/articles/377133.pdf
Data publikacji:: 2019
Wydawca:: Politechnika Poznańska. Wydawnictwo Politechniki Poznańskiej
Tematy:: fractional-order mutual inductance
fractional-order parameters identification
phase resonance
Opis:: The paper presents a method for identifying the parameters Lβ1, β1, Lβ2, β2, Mγ, γ of a fractional-order transformer. This method is based on the measurement of the phase resonance frequency in a few systems containing: the investigated fractional-order transformer and two standard capacitors. The dependencies allowing the determination of the fractional-order transformer parameters have been given, on the basis of the described measurements. The obtained results are illustrated by an example.

Tytuł:: DAQ-based measurements and study of supercapacitor frequency characteristics
Autorzy:: Sowa, Marcin
Jakubowska-Ciszek, Agnieszka
Powiązania:: https://bibliotekanauki.pl/articles/376459.pdf
Data publikacji:: 2019
Wydawca:: Politechnika Poznańska. Wydawnictwo Politechniki Poznańskiej
Tematy:: supercapacitor
frequency characteristics
data acquisition device
measurement card
fractional derivative
Opis:: The paper concerns the beginning of a modeling study for supercapacitors. A data acquisition (DAQ) based system is presented, where an automated procedure has been implemented for the measurement of frequency characteristics. For a typical range of the supply voltage the characteristics are obtained. A model basing on fractional calculus is recalled and parameters for the model are obtained. The frequency characteristics of the model are compared with those obtained from measurements. Later the tested supercapacitor has its characteristics taken for various amplitudes and offsets of the source voltage. A few remarks are given for a possible expansion of the model when nonlinearity should be considered.
