Mixed Actual and Memory Data-based Event-Triggered H∞ Control Design for Networked Control Systems

Abstract

Abstract In this paper, a new mixed event-triggered control scheme, based on the actual and memory sampled data, is proposed to reduce the network usage in Networked Control Systems (NCS) subject to network-induced delay. In this context, LMI-based conditions are provided from the selection of a convenient Lyapunov-Krasovskii functional, for the design of both the event generator for the proposed Mixed Event Triggered Control (METC) strategy and the associated memory-based sampled-data controller. The goal is to relax the number of transmitted packets, with closed-loop NCS stability guarantee, so that the network workload is mitigated. A numerical example is proposed to show the effectiveness and improvement of the proposed METC design procedure, regarding to some previous related results from the literature.
