Abstract:

In recent years, much effort has been devoted to the research of event-triggered schemes (ETSs) to save communication and computation resources in networked control systems (NCSs). In this paper, we propose a novel discrete event-triggered scheme (DETS) which uses multiple historical sampled-data to determine the next release instant. Compared to some existing ETSs, the proposed DETS can further reduce data transmissions and resource utilization. Considering the effect of the network, the closed-loop system is modelled as a time-varying delay system and stability criteria is established based on Lyapunov-Krasovskii method. The co-design of the controller gain and DETS parameters is achieved. An optimization algorithm is proposed to obtain the optimal DETS triggering thresholds. S imulation is carried out on a satellite control system, which validates the advantage of the proposed methods.
