Abstract :
The paper presents a model of a class of wireless network systems with delay and data dropout. The optimal state estimator is designed for the system by using time-varying Kalman filter on the basis of the presented model. Then, a design approach to feedback control of optimal state is presented. And the separation principle of state feedback controller and state observer is guaranteed by carrying the additional information in data packet. Finally, the stability of closed-loop NCSs is proven by applying MJLS theory.
