One class support vector machine (OCSVM) and one class minimax probability machine (OCMPM) are two domain-based single class classification methods and commonly used for fault detection. This paper systematically analyzes their training and detecting complexity, principle of optimization and hyperparameter influence of both methods, and compares their performance on motor and sensor fault data from the simulated traction control system of the high speed train. It shows that OCMPM achieves higher fault detection rate than OCSVM given the same false alarm rate. But OCMPM is unfeasible used for real-time fault detection when the training dataset is large.","PeriodicalId":353946,"journal":{"name":"2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126376102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attachments on blades will influence the system operation by causing imbalance and it is essential to monitor its working state, repair or replace the faulty blade (s) to reduce its damages. Imbalance fault detection of MCTs using electric signals has many superiorities compared with traditional vibration-based method. However, there are some shortcomings in using decomposition method to weaken the influence of waves and turbulence. This paper proposes a method to detect the imbalance fault of MCTs using voltage signal. In this proposed method, the instantaneous voltage frequency and average voltage frequency is calculated through Hilbert transform (HT). Meanwhile, the imbalance fault frequency is extracted by using the cubic spline interpolation. Finally, the wavelet transform (WT) method is used to detect whether there is a blade imbalance fault. The effectiveness of this method is verified by theoretical analysis, simulation results and experimental results.","PeriodicalId":353946,"journal":{"name":"2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126746747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The low-dimensional subspace of process variables can be found, which reflects real-time changes in quality. The detection rates of quality-unrelated faults can be reduced while the detection rates of faults that are related to quality are increased. The basic idea is to select the most relevant process variables and principal components (PCs) with the maximal part mutual information (PMI) for each iteration, so as to build a more accurate supervisory relations between process variables and quality. Afterwards, two appropriate statistics are established for quality-related fault detection. Finally, the Tennessee Eastman Process (TEP) is carried out to demonstrate the effectiveness of PMIQCA.","PeriodicalId":353946,"journal":{"name":"2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128112333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep Belief Network (DBN) has advantages in extracting features and processing high-dimensional, non-linear data, but the relevance of time series is not fully considered in training with time-dependent signals. The batch process has the characteristics of non-linearity, multiple working conditions and multiple time periods. Hence, DBN does not perform well in batch process. For this purpose, a method based on the combination of Long Short-Term Memory (LSTM) network and Deep Belief Network (DBN) is proposed. The method first adopts the preprocessing method of variable expansion and continuous sampling, and then uses DBN-LSTM network for feature extraction, time correlation analysis, and fault diagnosis. This method is applied to a class of semiconductor etching process. The experimental results show that the proposed method can effectively extract time-ordered nonlinear fault features from the original batch process data and has high fault diagnosis accuracy.","PeriodicalId":353946,"journal":{"name":"2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121191238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
