英文摘要：

Robust non-fragile H∞ state feedback control for uncertainty discrete singular systems was investigated, and the necessary and sufficient condition for the existence of controller was obtained. Furthermore, the desired controller was presented via linear matrix inequality. Finally, a numerical simulation illustrated this effectiveness of the proposed method.
