摘要：

This paper investigates a discrete-time domain design of unknown input functional observer (UIFO) for discrete-time linear singular delayed systems. Note that both constant and variable delays are considered. The main procedure is based on Lyapunov-Krasovskii stability theory, where the optimal gain in the functional observer is a solution of linear matrix inequalities (LMIs). Sufficient conditions for observer stability are proposed. The effectiveness of the proposed approach is illustrated by a numerical example.
