A model based networked control system is investigated in this paper, which is useful for realizing plant-level networked control of iron and steel processes. Sampled data of the state of a plant are transfered to a controller over a network with a communication delay. Then, a model based state feedback is introduced, which uses the model state instead of the plant state. An update rule is presented for resetting the model state appropriately based on the sampled data of the plant state. A necessary and sufficient condition of stability of the system is also derived as an eigenvalue test of a matrix.
