    Abstract
    This paper investigates the stability and stabilization of networked control systems under simultaneous consideration of control system performance and network dynamics. By constructing an information dispatching middleware, a framework of networked control systems is established. In terms of the middleware, a novel event-triggered scheme is developed to regulate the transmission of the sampled data by considering network dynamics. The main feature of the scheme is that the released sampled data is not only determined by the current control system state, and the error between the current data and the latest transmitted state ...

    This paper investigates the stability and stabilization of networked control systems under simultaneous consideration of control system performance and network dynamics. By constructing an information dispatching middleware, a framework of networked control systems is established. In terms of the middleware, a novel event-triggered scheme is developed to regulate the transmission of the sampled data by considering network dynamics. The main feature of the scheme is that the released sampled data is not only determined by the current control system state, and the error between the current data and the latest transmitted state of the control system, but also by the current state of the network dynamics. An augmented system of the proposed framework is formulated based on a fluid-flow model. By using Lyapunov-Krasovskii functional approach, sufficient conditions are derived for system analysis and synthesis, respectively. Under the proposed framework, a tradeoff is provided to balance the utilization of communication resources and the desired performance of the control systems. Finally, a numerical example is given to illustrate the merits and effectiveness of this proposed framework.
