Abstract
In this paper, we consider nonlinear discrete time systems modeled with polytopic uncertain linear systems. We develop the CPWL (Canonical Piecewise Linear) approach proposed by Labit [1] to the case of discrete time systems associated with the new discrete time stability condition proposed by de Oliviera [2] then improved by Daafouz [3]. The obtained linear matrix inequalities condition leads to necessary and sufficient, and less conservative control design condition. This method (Discrete time -CPWL approach and poly-quadratic stability) takes also advantages of the systematic design of robust controllers in one shot and the insuring scheduling for the nonlinear discrete time system control.

Abstract
Robust dynamic output feedback design is an open problem, computationally speaking, since its determination asks for the solution of nonlinear matrix inequalities, namely bilinear ones. This is particularly the case, for polytopic uncertainty. Here a new sufficient condition is proposed by the use of bounds and scaling for completion of squares. The usefulness of the provided conditions stands in the fact that its solution can be performed using the Frank-Wolfe algorithm which runs in only one shot. The control design of an inverted pendulum with uncertain friction coefficients illustrates the theory.
