This paper presents an overview on the studies of pinning control for complex networks over the past decade.Firstly,we summarize the pinning control algorithms for synchronizing complex networks.Then,based on network topology and node dynamics,some necessary or sufficient conditions for the pinning control of complex networks are discussed.For the pinning-controlled complex networks,we address the strategies for selecting the pinned nodes in detail,and comprehensively analyze the effects of the pinned-node number,the coupling strength,the pinning feedback gains and the node dynamics on the pinning control of complex networks.Moreover,we discuss the progress in the pinning control of signed networks where exist both cooperative and competitive relationships and provide some brief introduction for the application of the pinning control of complex networks.Finally,some suggestions are given to address the future research trends for the pinning control of complex networks.
