Abstract: This paper deals with the controller design of a multi-packet transmission networked control system with short time-delay and transmitted data dropout in static scheduling policy and in dynamic scheduling policy.The sensor failing to transmit data are treated to be invalidated temporarily and the networked control system is modeled as a system with time-varying sensors’ fault.The observer system is modeled as models of linear switched control systems under certain switching sequences whereas in static scheduling policy and the sufficient conditions for the asymptotic stability criterion are obtained with the theory of the fault-tolerant and periodical system and the observer system is modeled as a switched system with finite subsystems whereas in dynamic scheduling policy and the stability condition of the system is given with the theory of the fault-tolerant and switched system.And by using of the cooperative design approach of the controller and observer，the designs for fault-tolerant the control law and the state observer are presented.Numerical simulation examples demonstrate the conclusions are feasible and effective.
