基于奇异摄动方法的精馏塔模型简化及其仿真研究

Model Reduction of Distillation Columns via Singular Perturbation Method and its Simulated Investigation

将奇异摄动方法应用于一个精馏塔 ,得到具有三对角结构的动态简化模型。该文介绍模型简化的步骤 ,推导了简化模型的具体公式。仿真表明∶简化模型与全阶模型的静态和动态特性基本保持一致。

By applying singular perturbation to a distillation column, an order-reduced dynamic model with tridiagonal structure is obtained. This paper introduces the procedure of model reduction, and deduces the explicit expressions for the reduced model. The simulation results show that the static and dynamic properties of the reduced model are almost the same as that of the full model.
