| 摘 要： | 针对木糖醇发酵过程中木糖醇浓度不能在线测量和影响发酵过程控制的情况,使用软测量技术来估算木糖醇的浓度和底物浓度,使用动态BP网络作为软测量模型,并确定了10个隐含层节点的网络拓扑结构,使用LM算法训练网络。用未经训练的数据检验软测量模型,取得了满意的逼近效果。实现了木糖醇发酵过程木糖醇浓度和底物浓度的间接实时测量。

| Abstract: | Xylitol concentration cannot be measured on line,which can affect the control of the parameter in fermentation process.Considering this case,soft measurement technology is used to estimate the xylitol and the xylose concentration,and the dynamic BP neutral network(NN) is taken as the soft measurement model.The NN topology structure with ten nodes of hidden layer is determined.Levenberg-Marquardt arithmetic is used to train the net.From the test using untrained data,a good approach effect can be taken.The xylitol and xylose concentration can be measured in real time. |

| Keywords: | xylitol soft sensor neutral network(NN) fermentation |
