Robust H∞ dynamic output feedback synchronization for complex dynamical networks with disturbances

In this paper, the robust H-infinity dynamic output feedback synchronization problem for complex dynamical networks with disturbances is studied. A novel decentralized output feedback control scheme is proposed. For each node, a dynamic output feedback controller which is driven by local relative output measurements is constructed. By introducing the spectral decomposition technique, the closed-loop synchronization error system is proved to be robustly stable with an optimal H-infinity disturbance attenuation level. A simulation example of master-slave large scale system verifies the effectiveness of the proposed method. (C) 2015 Elsevier B.V. All rights reserved.
