Analysis and adaptive control for lag H∞ synchronization of coupled reaction-diffusion neural networks

In this paper, we respectively discuss the lag H-infinity synchronization of coupled reaction-diffusion neural networks with state coupling and spatial diffusion coupling. Based on the inequality techniques and Lyapunov functional method, some lag H-infinity synchronization criteria for these two coupled reaction-diffusion neural networks are obtained by exploiting the designed state feedback controllers. Furthermore, two adaptive strategies for ensuring the lag H-infinity synchronization of coupled reaction-diffusion neural networks with state coupling and spatial diffusion coupling are also developed. Finally, the effectiveness of the proposed lag H-infinity synchronization criteria is verified by two numerical examples. (c) 2018 Elsevier B.V. All rights reserved.
