Exponential input-to-state stability for Lur’e systems via Integral Quadratic Constraints and Zames-Falb Multipliers

Drummond, Ross; Guiver, Chris; Turner, Matthew

Abstract

Absolute stability criteria which are sufficient for global exponential stability are shown, under a Lipschitz assumption, to be sufficient for the a priori stronger exponential input-to-state stability property. Important corollaries of this result are: i) absolute stability results obtained using Zames-Falb multipliers for systems containing slope-restricted nonlinearities provide exponential input-to-state-stability under a mild detectability assumption; and ii) more generally, many absolute stability results obtained via integral quadratic constraint (IQC) methods provide, with the additional Lipschitz assumption, this stronger property.
