| 摘 要： | 由于发酵过程中,系统的非线性特性与发酵阶段密切相关,而应用常规MPLS时的静态单一模型、模型失配、不能充分有效压缩和抽取非线性信息、估计未来测量变量引入模型误差等问题,提出1种多阶段MPLS法.先采用ISODATA动态分类算法聚类分析过程数据,划分子阶段,针对各批次子阶段不等长的特点,再用DTW算法同步阶段轨迹,然后在...

| Abstract: | Fermentation processes have different nonlinear characteristics in different fermentation phases.A multi-phase multi-way partial least squares(MP-MPLS) method is proposed for handling the following problems:(1) static single model,(2) process and its model do not match, (3) linear method may not be efficient in compressing and extracting nonlinear process data,in the application of traditional MPLS method in actual industry.Using ISODATA clustering arithmetic,fermentation process data was divided into sever... |
