Abstract
This paper is devoted to the stabilization of sampled-data non-linear systems by output feedback receding horizon control (RHC). The output feedback consists of a stabilizing state feedback RHC and an observer for estimating the unknown states. Since the exact discrete-time models of sampled-data nonlinear systems are often unavailable, both the RHC and the observer are designed via an approximate discrete-time model of the plant. We established a set of conditions which guarantee that the output feedback RHC designed via an approximate discrete-time model practically stabilizes the exact discrete-time model of the plant.
