Abstract
This paper addresses the problem of local asymptotic stability analysis of multivariable linear systems with saturating controls. The nonlinear behavior of the closed-loop system is described by a polytopic model. From this description, a two-step procedure, based on the use of ellipsoidal and polyhedral contractive sets, is proposed in order to determine regions of local asymptotic stability for the closed-loop system. The procedure is numerically implemented from convex optimization and linear programming based algorithms.
