摘要:
研究使用BP 神经网络来完成化工过程的建模。一般的化工过程建模问题是非线性的问题。很多情形下, 与不同相有关 量的变化速率数量级相差很大, 从而问题是刚性的。这时, 用数值方法难于对过程的变化精确求解。由于BP 网络能实现任何 非线性的连续映照, 故适于处理复杂化工建模问题。将BP 神经网络用于精馏塔的温度计算, 结果令人满意。
Abstract:
A study on the modeling of chemical processes with BP neural networks is presented .Usually , the modeling problem of a chemical process is a nonlinear problem .In many cases, the quantitative dif ferences between the changing rates of variables related to different phases are quite great , thus the problems have a high stiffness , and it is difficult to solve the modeling problem accurately w ith the common digital calculation methods .It is showed that BP neural netw orks could perform any continuous nonlinear mapping .Hence they are suitable for handling complicated dynamic problem .In the paper a BP neural network is used to calculate the temperatures of the output flows of a fractionatio n tower .The results were satisfactory .
