A survey on recent advances in event-triggered communication and control

Event-triggered communication and control have been a hot research topic in networked control systems. This paper provides a survey on recent advances in event-triggered schemes, modelling, stability and controller design of event-triggered control (ETC) systems. First, a deep investigation is made into some existing event-triggered schemes, including event-triggered sampling schemes, self-triggered sampling schemes and discrete event-triggered communication schemes. Second, four notable models for ETC systems: hybrid system model, piecewise system model, perturbed system model and time-delay system model, are surveyed in detail. Third, various methods for stability analysis and controller design are summarized. Finally, several challenges in event-triggered communication and control are presented for future research.
