As a mechanism model can hardly reproduce the complicated dynamic characteristic s of a boiler superheater system, the authors have come up with a new modeling m ethod. The proposed method consists in taking the mechanism model as a main guid e and supplementing it with an on line correction through the use of a dynamic n eural network. The results of simulation indicate that such a model building met hod can provide an ideal approach for the dynamic simulation of a huge complicat ed system.
