A remark on a power gain inequality for interconnected systems

Abstract

Power gain is a simple generalization of L/sub 2/-gain that admits the analysis of a class of nonlinear systems with dynamics that exhibit an attracting set. In the paper, a notion of power gain is defined for interconnected systems. This power gain inequality allows the behaviour of the interconnected system to be described in terms of the component subsystems. A small gain theorem follows and an example is presented.
