Abstract

The state estimation of nonlinear coupled complex dynamical networks with time delay coupling is studied in this paper. The state estimation controllers are designed by using proportional control approach. A sufficient condition for state estimation is derived by using Lyapunov stability theory. Finally, we take the scale-free network as the network topology and the Lorenz chaotic system as the node dynamics, to do some simulations. The simulation results verify the effectiveness of the proposed method.
