Gain-Scheduled Output Control Design for a class of Discrete-Time Nonlinear Systems with Saturating Actuators
Résumé
This manuscript deals with the stabilization of a class of nonlinear discrete-time systems under control saturations including time-varying parameter dependency. The studied control law consists of the gain scheduled feedback of the measured output and of the nonlinearity present in the dynamics of the controlled system. Furthermore the saturations are taken into account by modeling the nonlinear saturated system through a deadzone nonlinearity satisfying a modied sector condition. Thus, as for precisely known systems, LMI stabilization conditions are proposed for such a generic system. These conditions can be cast into convex programming problems for design purposes. An illustrative example stresses out the eciency of the main result.
