On Pinning Control of Complex Networks
Abstract:
In this talk, pinning control of complex networks is presented and some particular control problems pertaining to large-scale dynamical networks are addressed and discussed. Given a network of dynamical systems (nodes) and a specific control objective (for example, controlled synchronization), assuming that a certain class of controllers such as local state-feedback controllers have been chosen to use, some typical questions about network control are how many controllers to use and where to apply them (namely, which nodes to pin) on the network, in order to achieve effective control with good performances. It is shown that the structural topology of the network is essential; therefore, how to utilize the topological features of the network (such as the node degree distribution, shortest path length and maximum betweenness centrality) is ultimately important. This raises many interesting and yet very challenging technical problems for systems control under a networking environment
