Quasi-synchronization of nonlinear time-delay coupled heterogeneous Lur'e networks

The heterogeneous networks with mismatched parameters cannot reach complete synchronization,but they can achieve quasi-synchronization,which means the state of each node in networks will keep a bounded error comparing with the target state.Quasi-synchronization is investigated for a class of nonlinear time-varying delay coupled heterogeneous Lur'e networks based on the aperiodically intermittent pinning control technique.By constructing a simple Lyapunov function,some sufficient conditions regarding the parameters are obtained to guarantee the heterogeneous networks to achieve quasi-synchronization through rigorous theoretical analysis.The validity and effectiveness of the theoretical results are verified by numerical simulation.

Key words:Lur'e network,quasi-synchronization,parameter mismatch,nonlinear coupling,time-varying delay,aperiodically intermittent control,pinning control
