| 摘 要： | 针对传统MPCA间歇过程故障诊断方法存在的在线数据不完整及实时性差缺陷，提出一种基于MFDA-PCA间歇过程的在线批次故障诊断方法．通过MFDA对在线批次正常部分与历史批次进行相似度分析，利用相似度最优的批次建立PCA模型，对在线批次数据进行实时分析，完成对整批生产过程在线监控及故障诊断的任务．最后以青霉素发酵仿真实验验证了该方法的有效性和快速性．

| Abstract: | Aiming at the traditional MPCA methods' defects of online data integrity and real-time differential,an approach for batch process fault diagnosis based on MFDA-PCA is proposed,which is easy to study the online fault diagnosis during the batch processes.At first step,MFDA model is used for analyzing similarity by comparing the normal times of online batch data with that of historical batches; next,an optimal similarity PCA model in historical batch processes is built to analyze online batch data;and then,the... |
