Regime-decomposing-oriented modeling approach to nonlinear thermal processes and its application
一种基于工况分解的热工过程非线性控制模型建立方法及应用

By taking into account the fact that most thermal processes have nonlinear characteristics dependent closely on operating regime,a nonlinear control oriented modeling method for thermal processes is proposed using a multiple model modeling approach based on operating regime decomposition.The proposed method was applied to build the nonlinear model of a 300?MW unit boiler superheater controlled process.The practical application results showed the nonlinear process model built by the proposed method remained valid over a wide range of operating conditions and the dynamic response of the model (agreed) well with that of the real plant,and proved the effectiveness of the method.
