Abstract :
This paper presents the functional observers design for linear fractional-order time-delay systems. Conditions for the existence of the these observers are given. Asymptotic stability of these observers are obtained from the fractional-order Lyapunov function. The gains of the observer are derived by using the linear matrix inequality approach. A numerical example is presented to illustrate our approach.
