摘　　要：鉴于机理模型很难再现锅炉过热器系统的复杂动态特性 ,本文利用机理模型为主导 ,动态神经网络在线修正 ,从而显著地提高了仿真模型的精度。仿真结果表明 ,此建模方法为复杂大系统的动态仿真提供了一个理想的建模途径。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.
