H∞ control theory in network output feedback controller design

Based on the network control system model of the general H_infin control theory and the basic concepts, with the introduction of interference to network control model, combined analysis of network delay on the network, this paper gives output feedback H_infin controller general model. Under the network delay is less than the sampling period, the control system of the network have an gamma-sub-optimal H_infin output feedback controller. In this paper, it gives the simulation results of single data packet transmission and packet loss, as well as the simulation result of the relationship between sampling period and maximum delay of under the setting performance target gamma.
