Abstract

In this paper, based on new definitions of passivity, some facts on preservation of stability and stabilization are inferred for commensurable fractional-order linear dynamica] systems, using the substitution of the variable s by the function s^α with 0 < α < 1. The main results are on preservation of "quasi-passivity", "quasi-strictly passivity"', H_∞-norm and coprime factorizations.
