This paper investigates an unknown input observer design for a large class of linear systems with unknown inputs and commensurate delays. A Luenberger-like observer is proposed by involving only the past and actual values of the system output. Sufficient conditions are given to guarantee the existence of such a Luenberger-like observer.
