The proposed method is applied to the identification of a 3-D RC network, which can be tailored in terms of topology and composition to emulate real-time systems governed by fractional-order dynamics. The results are in excellent agreement with the actual network response, yet the identification procedure only requires a small number of coefficients to be determined, demonstrating that the fractional-order modeling approach leads to very parsimonious model formulations.896-900enganalog circuit simulationFractional order systemsRC circuitssystem identificationArtigo10.1109/TCSII.2015.2436052Acesso aberto2-s2.0-849410681842-s2.0-84941068184.pdf887996458277884050620873805714620000-0002-1072-3814
