H ∞ Cluster Synchronization for a Class of Neutral Complex Dynamical Networks with Markovian Switching

الملخص EN

H ∞ cluster synchronization problem for a class of neutral complex dynamical networks (NCDNs) with Markovian switching is investigated in this paper.

Both the retarded and neutral delays are considered to be interval mode dependent and time varying.

The concept of H∞ cluster synchronization is proposed to quantify the attenuation level of synchronization error dynamics against the exogenous disturbance of the NCDNs.

Based on a novel Lyapunov functional, by employing some integral inequalities and the nature of convex combination, mode delay-range-dependent H∞ cluster synchronization criteria are derived in the form of linear matrix inequalities which depend not only on the disturbance attenuation but also on the initial values of the NCDNs.

Finally, numerical examples are givento demonstrate the feasibility and effectiveness of the proposed theoretical results.
