This article studies the asymptotical synchronization in mean square of reaction-diffusion neural networks (RDNNs) with random delays. A time-space sampled-data controller (TSSDC) is designed by sampling on both the time domain and spatial domain, which efficiently saves the network communication resources for RDNNs. A new processing method for the TSSDC is provided, capturing more sampling information and being more concise compared with existing methods. New mean square asymptotical synchronization criteria are established for RDNNs with random delays by constructing a sampling-dependent LKF, using the extended Poincare-Wirtinger inequality and Holder inequality, and the desired TSSDC gain is obtained. A numerical example is given to verify the effectiveness and superiority of the obtained results.
The asymptotical synchronization in mean square of reaction-diffusion neural networks (RDNNs) with random delays is studied in this article. By sampling on both the time domain and spatial domain, a time-space sampled-data controller (TSSDC) is designed, which can efficiently save the network communication resources for RDNNs. A new processing method for the TSSDC is provided. Compared with the existing methods, the processing method here can capture more sampling information and is more concise. An extended Poincare-Wirtinger inequality is proposed, which is in matrix form and less conservative. Then by constructing a sampling-dependent LKF, using the extended Poincare-Wirtinger inequality and Holder inequality, new mean square asymptotical synchronization criteria are set up for RDNNs with random delays, and the desired TSSDC gain is obtained. At length, a numerical example is given to verify the effectiveness and superiority of the obtained results.
