Stability analysis of fractional-order systems with double noncommensurate orders for matrix case

Abstract

Bounded-input bounded-output stability issues for fractional-order linear time invariant (LTI) system with double noncommensurate orders for the matrix case have been established in this paper. Sufficient and necessary condition of stability is given, and a simple algorithm to test the stability for this kind of fractional-order systems is presented. Based on the numerical inverse Laplace transform technique, time-domain responses for fractional-order system with double noncommensurate orders are shown in numerical examples to illustrate the proposed results.MSC 2010 : Primary 26A33; Secondary 33E12, 34A08, 34K37, 35R11, 60G22Key Words and Phrases: fractional-order systems, double noncommensurate orders, bounded-input bounded-output stability, numerical inverse Laplace transform technique

Stability analysis of impulsive fractional-order systems by vector comparison principle

“…[33]; the stability and synchronization results of fractional-order systems with noncommensurate order were given in Refs. [34] and [35]; almost sure stability of fractional-order Black-Scholes model was treated in [36]. Note that in [37][38][39] results about asymptotic stability of fractional-order systems were obtained by means of Lyapunov direct method.…”

Fractional operators in the matrix variate case

“…Laskin [4]). Further use of fractional integral operators related to real-valued scalar functions of matrix argument can be utilized for a fractional matrix calculus (Phillips [14]), numerical solution of fractional diffusion-wave equations (Garg and Manohar [2]), stability analysis of fractional-order systems (Jiao and Chen [3]), and probably for the application of the matrix-variate Mellin transform in radar image processing (Anfinsen and Eltoft [1]). …”

Tuning and implementation methods for fractional-order controllers

“…There is a number of applications in various areas, that were already published, for instance [6,13,17,20,23,31]. One important area of application is control theory.…”
