H∞ controller design of event-triggered networked control systems

This paper deals with H∞ controller 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. A new model of NCSs that involves the network conditions, state and event-triggered communication strategy is proposed. Based on this model, some novel criteria for the asymptotic stability analysis and H∞ state feedback controller 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.
