Delayed Impulsive Control for ?-Synchronization of Nonlinear Multi-Weighted Complex Networks with Uncertain Parameter Perturbation and Unbounded Delays

The global ?-synchronization problem for nonlinear multi-weighted complex dynamical networks with uncertain parameter perturbation and mixed time-varying delays is investigated in this paper. Unlike other existing works, all delays, including sampling internal coupling are assumed to be unbounded, making the considered model more general practical. Based on generalized impulsive comparison principles, a controller designed, some new sufficient conditions obtained make drive–response reach ?-synchronization. In addition, external matrices do not need meet requirement of zero-row sum, limitation time delay pulse interval weakened. results article can seen as extensions previous related research.
