Based on the theory of linear matrix inequality (LMI), the observer design for a class of nonlinear time-delay systems is studied. The sufficient condition for the existence of the gain matrix of the observer is obtained by choosing the appropriate Lyapunov-Krasovskii functional. The design of the gain observer is proposed systematically The simulation results show that the designed function observer is feasible and effective.
