Wirtinger's inequality is applied to event-driven output control of networked control systems with H∞ performance

This paper put forward Wirtinger's inequality method used to the analysis of Network control systems(NCSs) with the H infinity performance index level based on event-driven control. Firstly, the triggering mechanism of the event is represented by a delay model. Secondly, NCSs for the coupling between the controller,input matrix and the output matrix is eliminated by a new method The stable condition for the closed loop system with the Hoc performance index level can be obtained by Wirtinger's inequality and linear matrix inequalities(LMI). Finally, the validity of the filter design scheme is confirmed by a given numerical case.
