A novel distributed event-triggered control with time-varying thresholds

Event-triggered control has been widely used in the distributed networked control systems, since it has the advantages of reducing the frequency of information transmissions between subsystems, effectively saving communication resources and so on. A novel distributed event-triggered control with time-varying thresholds is designed in this paper. Under the event-triggering conditions, some sufficient conditions, to guarantee asymptotic stability of the corresponding distributed event-triggered control systems, are proposed. More importantly, the selection of parameters in the event-triggering conditions does not depend on the global structural parameters of the systems. In addition, it is proved that there is no Zeno behavior in the designed distributed event-triggered control systems. Finally, simulation examples are given to illustrate the efficiency and feasibility of the obtained results.
