Stabilization via reduced-order observer for a class of saturated linear systems

This paper addresses the problem of the global stabilization of a linear system with saturating controls by means of a dynamic output feedback using a saturated linear controller built from a reduced-order observer. It is shown that a simple specific linear control law of the optimal-like type always globally stabilizes the closed-loop system when the linear system to be controlled is stable (asymptotically or critically).<>
