Ying-you Sun, Guo‐Ping Jiang, Chunxia Fan · 2014
The state estimation of complex dynamical networks with time delay coupling under noisy transmission channel is studied in this paper. In order to suppress the effect introduced by the noise and time-varying delay, the state estimation controllers are designed by using integral control approach. A sufficient condition for state estimation is derived by using Lyapunov stability theory and H−Hcontrol technique. 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.
