AbstractIn this article, we aim to study the robust stabilization problem for a class of stochastic networked control delay systems with time‐varying delays and unknown parameters. By developing an event‐triggered strategy, the robustly exponential stability in mean‐square of the suggested system with an performance is obtained. Furthermore, the robustly exponential stabilization problem in mean‐square is also solved by designing an controller. Compared with many published results in the literature for discrete‐time stochastic systems, our work mainly focuses on the case of continuous‐time stochastic systems. In particular, time‐varying delays and unknown parameters are also considered. Finally, the applications of the theoretical results are illustrated by two numerical examples.
