Abstract :
This paper presents a novel solution to the sliding mode output feedback control for uncertain discrete-time systems, which is aimed at electronic embedded motion control of implementation designs. The uncertainty is considered mismatched and with an unknown bound, which is identified by the proposed dead-zone adaptive law. The uncertain discrete-time system is made asymptotically stable under the proposed adaptive sliding mode output feedback control, which is based on the multirate sampling technique. Finally, a numerical example demonstrates the effectiveness and feasibility of the proposed control strategy.
