Extended Dissipative Analysis And Control For Network Control Systems With An Event-triggered Scheme

In order to reduce the unnecessary waste of the limited network bandwidth resources,more and more researchers have focused their attention on the event-triggered control in the context of networked control systems(NCSs)in recent years.As a new performance index,extended dissipation provides a more effective way to solve the control problem of complex systems.However,as far as the authors know,the extended dissipative has not been used as the performance index of network control system.In this paper,the extended dissipative analysis and control for several event-triggered network control systems are discussed.The main contents are as follows:1.For a class of network control systems.Firstly,the proposed system is modeled as a network control system with a discrete event-triggered scheme.Then,by using the integral inequality and improved reciprocally convex inequality technique,sufficient condition to guarantee the extended dissipativity of the network control systems is given in terms of linear matrix inequalities(LMIs).On this basis,the controller feedback control gain and event-triggered parameters are co-designed.2.For a class of networked stochastic systems,the problem of extended dissipative analysis and a non-fragile feedback controller is designed.Considering the effect of network-induced delay,an event-triggered time-delay stochastic system is formulated by introducing an event-triggered scheme in the closed-loop system.By multi-delay partitioning method,some delay-dependent criteria are proposed to ensure the system statisfies extended dissipative performance.In addition,two non-fragile state feedback controllers are designed to ensure that the closed-loop system satisfies the extended dissipative performance.3.For a class of singular networked control systems,the problem of extended dissipative is discussed.Firstly,by introducing a class of non-uniform sampling mechanism,the system is modeled as singular time-delay system by using the time-delay system method.A time-dependent functional is constructed and a sufficient condition for determining the system to satisfy the extended dissipative proformance is obtained.Furthermore,the state feedback controller is designed to ensure that the closed-loop system satisfies the extended dissipative performance.
