A characterization of integral input-to-state stability. (English) Zbl 0979.93106

The authors present several necessary and sufficient Lyapunov-like characterizations of the integral input-to-state stability property in terms of dissipation inequalities and a zero-detectability condition allowing the application of the LaSalle invariance principle. The notion of integral intput-to-state stability generalizes the concept of finite gain allowing to quantify sensitivity in the presence of nonlinear resonance. The paper ends with a counter-example which exhibits a forward complete and 0-GAS system which has not the integral intput-to-state stability property.
