Abstract

This paper focuses on global stability analysis problems for interconnected nonlinear systems. The main purpose is to introduce a useful parameterization into supply rates of dissipative nonlinear systems for establishing global stability via the input-to-state stable(ISS) small-gain condition. Supply rates which are parameterized by state-dependent scaling provide us with convenient flexibility to determine a proper function that matches a system and leads us to desired stability. Stability criteria proposed in this paper are more advantageous to uncertain systems analysis and design than the primary versions of state-dependent scaling criteria presented in previous papers.
