Abstract

This paper deals with the problem of event-triggered non-fragile H∞$$ {H}_{\infty } $$ control for networked control systems (NCSs) with time-varying delay. The first step is to design a thorough dynamical framework for NCSs that includes uncertainty components. This framework incorporates time-varying delays, external disturbances, and parameter uncertainty. The closed-loop system with a non-fragile term is integrated into the event-triggered scheme (ETS) via Lyapunov-Krasovskii functionals (LKFs), ensuring the system is asymptotically stable (AS). Furthermore, the design conditions for H∞$$ {H}_{\infty } $$ controller performance are formulated, and our results are expressed in terms of linear matrix inequalities (LMIs). The consequences of the suggested strategy are demonstrated numerically using MATLAB ®$$ {}^{\circledR } $$ with different parameter settings. These results demonstrate that the proposed strategy surpasses existing approaches, showcasing its superiority.
