Abstract :
In this paper, an impulsive controller is designed to achieve exponentially lag synchronization for coupled uncertain unified chaotic systems with stochastic perturbation. Based on a comparison principle for stochastic impulsive systems, drive-response concept and linear matrix inequality (LMI) approach, several easily verified and realistic sufficient conditions in terms of linear matrix inequalities are derived to guarantee exponentially lag synchronization between the drive system and response system. Moreover, the exponential decay rate has been estimated. A numerical example is provided to validate the effectiveness of the proposed scheme.
