Abstract After networked control systems (NCSs) are formalized in a class of time‐delay control systems, Lyapunov–Krasovskii functions (LKFs) can be employed to investigate the control system stability. While different LKFs and various manipulations of them may lead to differing results regarding the capacity of the time delay, the results presented in this paper demonstrate that the conditions guaranteeing system stability can tolerate larger time delays by employing a unique LKF that leverages the characteristics inherent to NCSs. In addition, a novel event‐triggered control (ETC) scheme is presented, which prevents the persistent violation of predetermined conditions caused by network‐induced time delays, along with a state‐feedback controller. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
