State feedback control for networked control systems based on state observer

The problem of state feedback control for networked control systems (NCSs) based on state observer is investigated. Suppose that the sensor node is time-driven, the controller and the actuator are event-driven, and the uncertain time-delay which is less than or equal to one sampling period, an augmented model for NCSs is developed. By using linear matrix inequality (LMI) formulation, the conditions of the asymptotical stability for NCSs are derived. Furthermore, the designs for the control law and the state observer are presented. A numerical simulation example shows the effectiveness of the analysis method.
