英文摘要：

Combining the event-triggered sampling and state observer designing method, a synchronization model for chaotic systems is proposed based on event-triggered sampling. Then, a sufficient synchronization condition is constructed by Lyapunov stability theory, and the synchronization algorithm is proposed by using of Matlab software. Finally, the effectiveness of the proposed algorithm is verified by the simulation of the Chua＇s circuit systems, which shows that the algorithm is easy to implement and has good synchronization effect. Furthermore, it can also reduce the sampling times to a certain extent.
