Abstract
A family of switched systems is exponentially stable if there exists positive constants
M and  such that the solution at time t satis es an estimate of the following
kind jx(t)j  Me t jx(0)j, for all possible switching sequences. Clearly exponential
stability implies attractivity of the origin; we show that for homogeneous systems
(and as a special case for linear systems) the converse implication is also true.
Key words: stability properties, Lyapunov methods, switched systems, robust
stability
1 Introduction and basic de nitions
The study of switched systems is a fastly growing area of research in control
theory. Informally a switched system is a dynamical system which is able to
commute between di erent behaviours according to some external input vari-
able, which we will in the following refer to as switching signal. The practical
