Robust input-output decoupling via static measurement output feedback

Abstract

In this paper the problem of robust input-output decoupling for linear systems with nonlinear uncertain structure (NLUS), via an independent from the uncertainties static measurement output feedback law, is studied. The necessary and sufficient conditions for the problem to have a solution, are established. The general analytical expressions of the feedback matrices and the decoupled closed loop system are derived. The problem of robust input - output decoupling with simultaneous Hurwitz invariability, is also studied.
