Abstract

In order to ensure the system performance while considering the economic utilization of network resources, this paper investigates the problem of the L₂-L_∞ control for a class of distributed-delay networked control systems (NCSs) with model parameter uncertainty under the event-triggered mechanism (ETM). Firstly, a non-fragile state feedback controller model structure with different time-varying parameter matrices is adopted. Secondly, the time-varying delay information combined with the ETM is considered in stability analysis, based on the delay-dependent Lyapunov-Krasovskii functional and the free weight matrix method, sufficient conditions are obtained to guarantee the robust asymptotic stability and the L₂-L_∞ performance of the closed-loop system. Then the co-design method of the controller and the ETM is given by using linear matrix inequalities (LMIs). Finally, the feasibility of the co-design scheme is verified by a numerical example and some comparison results. Compared with some existing works, the proposed method leads to larger inter-event transmission intervals, which can save network resources while preserving the desired control performance.
