摘要
This paper puts forward a new free-weight matrix method used to analyse Network control systems (NCSs) with the H infinity performance index level based on event-driven control. Firstly, design a relative triggering mechanism contain the measured output for a linear system with external disturbances. Secondly, in order to reduce the conservativeness an appropriate Lyapunov-Krasovskii function is constructed. For the integral term generated after the above functional derivation, the free-weight matrix inequality is selected for scaling. Finally,the sufficient condition that the closed-loop system represented by the linear matrix inequality (LMI) satisfies the H infinity performance index and the solution of the controller are obtained.The validity of the scheme is confirmed by a given numerical case.
