Abstract

This article investigates the synchronization issue of stochastic large-scale networks with time delays (SLNTD) via periodic self-triggered asynchronous intermittent sampled-data decentralized control (PAISC). This is the first implementation of asynchronous decentralized control to tackle asynchronization challenges in intermittent sampled-data control. Particularly, the self-triggered characteristic of the controller facilitates adaptive adjustments in response to exceptional circumstances, thus bolstering the fault tolerance capabilities of SLNTD. Methodologically, the Lyapunov method is utilized to analyze the

p

th moment exponential synchronization of SLNTD, incorporating the method of graph theory to process asynchronous-meaning cross-coupling terms. Moreover, the practical merits of our obtained results are illustrated through the numerical example of islanded micro grid. Finally, a numerical example is given to illustrate the asynchronous advantages of PAISC.
