Abstract

This paper uses the Euler method to a delayed chaotic system, resulting that a time-discrete drive system is obtained. And then a time-discrete response system with negative feedback and impulsive effect is designed. Some sufficient conditions are given to ensure that the drive-response systems are globally impulsively exponentially synchronized. At last, the effective and the feasibility of the drive-response systems are illustrated by some numerical examples.
