Unstable equilibrium points stabilization of complex dynamical networks using output-feedback pinning control

In this paper, we address the stabilization of unstable equilibrium points for a complex dynamical network by using output-feedback pinning control method. A controller is proposed for stabling the unstable equilibrium points of the network by using output signals of partial nodes of the network. The controller parameters are designed based on Lyapunov theory. Simulations are given for global coupling network, the nearest neighbor coupling network, the scale-free network and the small-world network, showing the effectiveness of the proposed method.
