Although many objectives involving the time-delay system exist, the time-delay systems are often dealt as a finite dimensional system by using Pade approximation, etc. This paper presents a design of a continuous-time adaptive observer for the linear system with the unknown time delay without using such a approximation. To our best knowledge, no research result of an adaptive observer for the unknown time-delay system designed without the approximations is proposed until now.
