摘要

A method is proposed for synthesizing output feedback controllers for nonlinear Lur';e systems. ne problem of designing an output dynamic controller for uncertain-free systems and systems subject to multiplicative norm-bounded perturbations in the linear part were proposed respectively. The procedure is based on the use of the absolute stability, through the circle criterion, and a linear matrix inequalities (LMI) formulation. The controller existence conditions are given in terms of existence of suitable solutions to a set Of parameter-dependent LMls.
