Abstract:: This paper primarily investigates the adaptive synchronization of a class of time-delay chaotic sys-tems with uncertainties. According to Lyapunov-Krasovskii functional and the Lyapunov stability theory,thecontroller and adaptive law are designed. The control strategy does not contain time-delay terms,which can beapplied to time-delay or multiple time-delay chaotic system,whoes time-delay is known or unknown.The ap-proach is more robust to noise and external interference,and does not need to known the upper bound of un-certainties in advance. In addition,it can adjust the system response rapidly by adjusting the accelerated fac-tor. Numerical simulations verify the effectiveness of the proposed method.
