Abstract

Pinning control of synchronization over complex dynamical networks is addressed. Notion of synchronization and some criteria are firstly introduced for various dynamical networks, such as fully-connected, ring-shaped and star-shaped regular networks, as well as small-world and scale-free complex networks. Notion of pinning-controlled synchronization is then discussed, for networks that do not satisfy self-synchronized conditions. Some commonly concerned questions are also discussed, such as what kind of controllers to deploy, how many to use, and where to apply them on a given network, so as to achieve effective network synchronization. A simple state-feedback pinning control method is finally introduced, supported by numerical simulation examples.
