This paper investigates a decentralized event-triggering communication scheme for large-scale systems under network environments. First, a decentralized event-triggering communication (DETC) scheme for large-scale systems is proposed, which does not require that all transmitted nodes are synchronous. Second, a heuristic algorithm is presented to optimize the parameters of DETC to reduce the occupancy of the network resources induced by DETC. Third, by constructing a novel Lyapunov–Krasovskii functional, a stability criterion and a stabilization criterion are derived for ensuring that the solution of studied system is uniformly ultimately bounded (UUB). Compared with some existing emulation-based methods, the controller gains in this paper are no longer required to be known a priori. Finally, an example is given to show the effectiveness of the proposed approach.
