This paper focuses on the problem of adaptive robust output tracking for delayed chaotic systems with sector nonlinearity in input function. Based on Lyapuvov-Krasovskii function, an adaptive robust controller is proposed. It is also shown that the proposed feedback controller can guarantee that the error between state x(t) and delay state x(t — τ) is uniformly ultimately bounded. Finally, a Chua's circuit is given to illustrate the validity of the proposed control scheme.
