| 摘 要： | 针对发酵过程观测数据与时序相关,提出一种动态多方向偏最小二乘回归(MPLS)方法,该方法的多模型结构解决了非线性和实时性的问题,更加适用于发酵过程的在线预报,与人工神经网络(ANN)方法相比,动态MPLS回归模型可以达到更好的拟合和预报精度.对青霉素发酵过程的效益函数拟在线预报,验证了该方法的准确性和有效性.

| Abstract: | A dynamic multiway partial least square regression(MPLS)method is proposed.Using multi-model of this method instead of single model,the problem of nonlinear and real-time can be solved.So it is especially suitable to on-line predict fermentation process.Compared with artificial neural network(ANN),the accuracy and speed of process prediction are all improved.Online prediction of the profit function for penicillin fermentation process is studied;the results demonstrate that the method is proper and effective. |
