基于改進(jìn)多模型FDA的間歇生產(chǎn)過(guò)程的故障診斷
Abstract:Since there are not enough fault data in historical data sets, it is very difficult to diagnose faults for batch processes. In addition, a complete batch trajectory can be obtained till the end of its operation. In order to overcome the need for estimated or filled up future unmeasured values in the online fault diagnosis, sufficiently utilize the finite information of faults, and enhance the diagnostic performance, an improved multi-model Fisher discriminant analysis is represented. The trait of the proposed method is that the training data sets are made of the current measured information and the past major discriminant information, and not only the current information or the whole batch data. An industrial typical multi-stage streptomycin fermentation process is used to test the performance of fault diagnosis of the proposed method. 作者: 蔣麗英 謝磊 王樹(shù)青 Author: JIANG Liying XIE Lei WANG Shuqing 作者單位: 浙江大學(xué) 期 刊: 中國(guó)化學(xué)工程學(xué)報(bào)(英文版) ISTICEISCI Journal: CHINESE JOURNAL OF CHEMICAL ENGINEERING 年,卷(期): 2006, 14(3) 分類(lèi)號(hào): N94 Keywords: fault diagnosis Fisher discriminant analysis batch processes 機(jī)標(biāo)分類(lèi)號(hào): TP3 S63 機(jī)標(biāo)關(guān)鍵詞: 多模型 間歇 生產(chǎn)過(guò)程 故障診斷 Discriminant Analysis fault diagnosis discriminant analysis fermentation process batch processes diagnosis of 基金項(xiàng)目: 國(guó)家自然科學(xué)基金 基于改進(jìn)多模型FDA的間歇生產(chǎn)過(guò)程的故障診斷[期刊論文] 中國(guó)化學(xué)工程學(xué)報(bào)(英文版) --2006, 14(3)蔣麗英 謝磊 王樹(shù)青Since there are not enough fault data in historical data sets, it is very difficult to diagnose faults for batch processes.
