The results of process monitoring indicate that this method is more effective than the process monitoring method based on conventional blind source signal separation. 6 ) due to the complexity of process information, a process monitoring method which applies independent component analysis and principal component analysis to extract nonnormal distributed process features and normal distributed process features is presented, which avoids the assumption that process information is subjected to multivariate normal distribution
8 ）鑒于在過程中，過程信息的平穩性並不確定，提出了一種不考慮過程平穩性能的過程監控方法，模擬表明該方法比基於傳統ica的過程監控方法具有更少的誤報率和漏報率，而比基於mspc的過程監控方法具有更少的誤報率，從而說明該方法的有效性。 -
Two primary mathematical tools used in this dissertation are principal component analysis ( pca ) and blind signal analysis ( bsa ), which are both data - driven methods. pca is not only used as feature extracting method ( where process variables are subjected to multivariate normal distribution ), but also as a tool for dimension reduction ; bsa is used to extract independent features or process blind source signals from process information in information theory sense, which is more effective than pca in describing the process
主元分析方法不僅作為一種過程特徵的提取方法（在過程信息服從多元正態分佈的情況下） ，而且也作為一種過程數據降維的主要工具（在過程盲源信號提取的情況下） ；盲源信號分析是從信息論的角度，從過程信息中提取出盡可能獨立的過程特徵信號或過程原始信源信號，它具有比主元分析更好的刻畫過程運行特徵的性能。
