Abstract:

An H∞ synchronization control scheme is proposed for timevarying delayed chaotic neural networks with secure information. When the synchronization of timevarying delayed chaotic neural networks is achieved, the secure information can be efficiently recovered. Using linear matrix inequality (LMI) technology, the H∞ synchronization controller is proposed and the convergence of the synchronization error is analyzed using the Lyapunov method. After the synchronization error is satisfied, the hidden information can be obtained  according to the states of the slave chaotic neural network system. Simulation results demonstrate that the proposed  H∞ synchronization scheme can efficiently achieve the synchronization between two time varying delayed chaotic neural networks and multi-channel signals can be recovered.
