Abstract

In this paper, a delay dependent robust fuzzy output feedback control is considered for time-delay chaotic systems with disturbances. Observer based controller is constructed by the T-S fuzzy model. The control algorithm is proposed to guarantee the H_infin performance of the time-delay chaotic systems. Linear matrix inequality (LMI) method is used to obtain controller and observer gains. To find the minimum attauation level, full positive symmetric matrices, P, R, S, T and U, are used. A numerical example is also presented to demonstrate the effectiveness of the proposed method.
