| 摘 要： | This paper deals with the issue of synchronization of delayed complex networks. Differing from previous results,the delay interval 0,d(t)] is divided into some variable subintervals by employing a new method of weighting delays. Thus,new synchronization criteria for complex networks with time-varying delays are derived by applying this weighting-delay method and introducing some free weighting matrices. The obtained results have proved to be less conservative than previous results. The sufficient conditions of asymptotical synchronization are derived in the form of linear matrix inequality,which are easy to verify. Finally,several simulation examples are provided to show the effectiveness of the proposed results.

The sufficient conditions of asymptotical synchronization are derived in the form of linear matrix inequality, which are easy to verify.
