A multi-mode fault diagnosis model is proposed by composing of multiple recurrent neural networks (MRNN) in parallel, in which only one model is built for the complex modes without identifying mode information in advance. Parallel RNN modules are combined appropriately into the model to judge whether the current state of process operation is faulty from different perspectives, so as to achieve the similar effect of modeling a class of working modes for each module. Several fault prediction and training strategies are also studied for this model and the suitable strategy is proposed. The simulation data of the multi-mode process are generated through the Tennessee Eastman process to verify the effect of the proposed model.","PeriodicalId":412672,"journal":{"name":"2022 IEEE 11th Data Driven Control and Learning Systems Conference (DDCLS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130187651","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}

In this work, to fully extract the spatial and temporal information of EEG for MI decoding, we designed an end-to-end compact deep convolutional neural network model, combining EEGNet and a temporal convolutional network. The proposed model requires few data pre-processing and a small number of trainable parameters, achieving significant performance improvement on MI-EEG decoding tasks.

In this paper, automatic relevance determination (ARD) method which based on Gaussian process regression (GPR) is proposed to select the appropriate input variables. The ARD method considers the nonlinear mapping relationship from input variables to the output variable. Moreover, the wastewater treatment plant is modeled by GPR, which requires fewer model parameters and can give a confidence interval.

Affected by closed-loop feedback, process data often demonstrate certain dynamic characteristics. In addition, traditional soft sensor methods are often based on the assumption of completeness. Once part of the data is missing, the above methods will collapse. In this paper, we propose a Spatio-Temporal view Generative Adversarial Imputation Network (GAIN) for data imputation and apply dynamic soft sensor for block missing accompanied with completely random missing data. Initially, a data pre-imputed strategy is designed to first impute the missing data through GAIN from the perspective of data distribution. Secondly, on the basis of pre-imputation, a data imputation strategy that integrates time and space information is proposed to impute the data precisely, which can comprehensively consider the time series of process data and the correlation between variables, and further improve the accuracy of data imputation. Finally, we propose a dynamic soft sensor method to make real-time predictions of the data.

Long-short-term memory (LSTM) network and feature extraction of contrastive predictive coding (CPC) are used in this paper for building deep learning models. CPC can learn representations of data, and LSTM can learn the information contained in sequence data. For application to fault diagnosis, the whole model combining CPC and LSTM can appropriately distinguish normal data from various fault data. Experiments on the Tennessee-Eastman process show that the LSTM model combining with proper feature extraction methods can improve the performance of fault diagnosis.","PeriodicalId":412672,"journal":{"name":"2022 IEEE 11th Data Driven Control and Learning Systems Conference (DDCLS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471177","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}

Therefore, it is necessary for construction workers to wear safety helmets on construction site, which saves their lives on sudden accidents. The traditional way to handle helmet wearing issue is through manual inspection and video surveillance, which has poor efficiency and lacks immediate warning. To solve this issue, the authors propose a helmet wearing detection approach based on YOLOv5 and annotate a dataset with 3, 965 images. Then, the authors divide labelled dataset into training set (3, 108 images) and validation set (857 images) to train the neural network with the pre-training weight YOLOv5s.pt. Lastly, the authors use the trained neural network to predict real scene images collected from the construction site. Experimental results indicate that safety helmet wearing detection using the trained YOLOv5 network performs well in term of high precision rate, high recall rate, low training classification loss, and low training objectness loss. In addition, it is capable of detecting safety helmets precisely as well as making a fair distinction between different categories.","PeriodicalId":412672,"journal":{"name":"2022 IEEE 11th Data Driven Control and Learning Systems Conference (DDCLS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126675477","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}

In the design process, the linear quadratic optimal control is combined to design an optimal sliding mode surface, based on which an optimal discrete-time sliding mode controller is derived by using a modified Gao's reaching law.
