Delay-dependent impulsive control for lag quasi-synchronization of stochastic complex dynamical networks.

In this paper, the globally exponential lag quasi-synchronization problem of stochastic complex dynamical networks with impulsive control is studied. Sufficient conditions ensuring the exponential lag quasi-synchronization in mean square for the systems with and without communication delay are obtained by using some important inequalities, Lyapunov function and Itô formula respectively. The results show that the lag quasi-synchronization of stochastic complex dynamical networks can be realized by using the impulsive control method. Two numerical examples are also given to verify the effectiveness of the theoretical results. [ABSTRACT FROM AUTHOR]
