Abstract

This paper is devoted to the problem of output feedback sliding mode control for uncertain discrete-time systems. To this end, a hybrid state and disturbance observer is proposed, and the corresponding observation errors are estimated. Based on the observed states and disturbances, an output feedback controller is designed to achieve quasi sliding mode, in which the matching and linear boundary conditions for uncertainties are removed. A numerical example is included to illustrate the obtained results.
