Pinning cluster synchronization of delayed complex dynamical networks with nonidentical nodes and impulsive effects
This paper studies the exponential cluster synchronization problem of complex dynamical networks with delayed couplings and nonidentical nodes. A new type of pinning impulsive control approach is proposed to achieve the exponential cluster synchronization of the considered network. By employing a time-dependent Lyapunov functional, less conservative cluster synchronization criteria are established in the form of linear matrix inequalities. Compared with the existing works, the constructed Lyapunov functional is related with impulse time sequence, which makes full use of the information on dynamical characteristic of synchronization error dynamics. Finally, a numerical example of typical chua’s system is given to illustrate the effectiveness and correctness of the theoretical results.
