Abstract
In this brief, a new Lyapunov-function-based event-triggered mechanism is proposed to investigate the state feedback control of nonlinear discrete-time cyber-physical systems. By summing the difference of Lyapunov-function between two adjacent events and utilizing it to construct the triggering law, the asymptotic stability of system can be ensured without demanding the difference of the Lyapunov function to be negative at any time. Thus, a larger inter-execution time under this scheme can be obtained than the conventional event-triggered mechanism. Meanwhile, the application of this scheme to linear systems is also presented. Finally, some simulations are implemented to show the advantages of the developed strategy.
