Event-triggered H_∞ filtering for networked control systems with time-varying delay

Abstract

This paper deals with the H _∞ filter design problem for event-triggered networked control systems (NCSs), where the next task release time and finishing time are predicted based on the sampled states. The closed-loop filtering error system is modeled as a linear system with an interval time-varying delay and event-triggered communication strategy. Based on this model, some novel criteria for the asymptotic stability analysis and H _∞ filter design of the event-triggered NCSs with time-varying delay are established to guarantee a prescribed H _∞ disturbance rejection attenuation level. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method.
