Abstract
Linear integer-order circuits are a narrow subset of rational-order circuits which are in turn a subset of fractional-order. Here, we study the stability of circuits having one fractional element, two fractional elements of the same order or two fractional elements of different order. A general procedure for studying the stability of a system with many fractional elements is also given. It is worth noting that a fractional element is one whose impedance in the complex frequency s-domain is proportional to s? and ? is a positive or negative fractional-order. Different transformations and methods will be illustrated via examples. © 2007 Elsevier Ltd. All rights reserved.
