Output feedback ℋ∞ synchronization for delayed chaotic neural networks

In this paper, we propose a new output feedback ℋ∞ synchronization method for delayed chaotic neural networks with external disturbance. Based on Lyapunov–Krasovskii theory and linear matrix inequality (LMI) approach, the output feedback ℋ∞ synchronization controller is presented to not only guarantee stable synchronization, but also reduce the effect of external disturbance to an ℋ∞ norm constraint. The proposed controller can be obtained by solving the LMI problem. An illustrative example is given to demonstrate the effectiveness of the proposed method.
