In order to reduce the communication burden of networks, for systems with fixed networked-induced delays and
random data packets dropout, the system is augmented to eliminate the effect caused by networked-induced delays. Then the augmented system is converted into a switched system to include the data packets dropout. Based on the switched system model, the design method of networked robust controller is proposed, which only adopts the feedback system state of original system and can reduce the communication request. Finally, a simulation example shows the effectiveness of the results.
