The paper studied a type of network control system with communication delay and model uncertainty. By adding, a system state predictor to the controlled system of the network system, based on observer a state feedback controller was designed to ensure the system stable with event triggering strategy. Firstly, a state observer was designed based on measure output of system. Secondly, to deal with communication delay in network, we proposed a state predictor, which can calculate the future system state after h time. Compared to the system state only use event trigger strategy the number of times the control signal is triggered significantly reduced, and control channel saves communication resources. In the third place, contacted with event trigger strategy the state feedback in the form of Linear matrix inequality (LMI), and eliminate the influence of communication delays. Meanwhile, it can proved that there is no Zeno phenomenon in the controlled system. At last, the effectiveness of be designed event trigger control is verified by numerical simulation.
