Event-triggered Pinning Synchronization of Multi-weighted Coupled Neural Networks without and with Time Delays

This paper solves event-triggered pinning synchronization problem for multi-weighted coupled neural networks (MWCNNs) without and with time delays. On one side, by designing appropriate event-triggered controller, a pinning synchronization criterion for MWCNNs under the designed event-triggered condition are derived based on the Lyapunov functional method and some inequality techniques. On the other side, we also investigate the event-triggered pinning synchronization of multi-weighted coupled delayed neural networks (MWCDNNs) and eatablish a corresponding synchronization criterion based on the suitable event-triggered pinning controller and condition. Finally, an example with numerical simulation results is provided to illustrate the effectiveness of the obtained theoretical results.
