Event‐triggered non‐fragile H∞ control for uncertain networked control systems with time‐varying delay

ABSTRACT This paper deals with the problem of event‐triggered non‐fragile 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 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 with different parameter settings. These results demonstrate that the proposed strategy surpasses existing approaches, showcasing its superiority.
