The Youla parameterization for nonlinear feedback systems with additive disturbances

Abstract

Building on the work presented in [9, 10, 11, 121, a construction of the Youla Parameterization for nonlinear feedback systems is presented in which the feedback loop is disturbed by additive disturbances. The construction of the Youla parameterization of [9, 101 may then be shown to be stable and wellposed in the presence of external disturbances.
