Besides, we also use the data augmentation strategy of SpecAugment to further improve the system. The experiments on Aishell-1 dataset show that bi-directional (Bi-SRU) outperforms BiLSTM as encoder, and some optimization strategies like label smooth and scheduled sampling also improve the accuracy. The model trained using Bi-SRU and SpecAugment achieves the best performance in the experiments.","PeriodicalId":6767,"journal":{"name":"2020 IEEE 3rd International Conference on Automation, Electronics and Electrical Engineering (AUTEEE)","volume":"146 1","pages":"268-271"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77745595","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 approach, the impact of internal parameter uncertainties and external disturbances on the closed-loop system performance is suppressed. Advance prediction of the target dynamics is achieved by Singular Value Decomposition-Unscented Kalman Filter (SVD-UKF), which reduces response lag caused by Tracking Differentiator (TD) in ADRC and visual processing. To realize optimal performance of P-ADRC, the Adaptive Particle Swarm Optimization (APSO) is used to overcome the problems of numerous parameters and difficulty in tuning.

Machine learning has brought out a series of high-performance convolutional neural networks (CNN) that work well in noise level estimation.

As a result, a model based on a pre-trained Visual Geometry Group-16 network with additional regression layers was created in this research. It was then trained with a dataset that contained a series of images with different levels of additive white Gaussian noise. The results showed high performances in all ranges of the noise levels and were relatively competitive among some other algorithms. In all, a pre-trained convolutional network can estimate the noise level as accurately as some classic algorithms, and it even performed better in the high noise level range. The whole processing would be far simpler, compared to the traditional method, since CNN does not require setting parameters once the training is done.","PeriodicalId":6767,"journal":{"name":"2020 IEEE 3rd International Conference on Automation, Electronics and Electrical Engineering (AUTEEE)","volume":"47 1","pages":"492-495"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78020122","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}

By the end of 2019, 110kV and above XLPE cables in operation have exceeded 30,000 kilometers in China. At present, some XLPE cables in operation have entered the late stage of aging or have reached the design life. How to effectively evaluate the operation risks of XLPE cable lines and arrange cable asset management strategies has become an urgent problem in the field of high-voltage cables. In this paper, a high voltage cable system risk assessment model based on cable fault probability and fault loss is proposed from two aspects of cable state health and importance. Cable state health is characterized by the probability of cable failure. By combining the Weibull distribution and the cox risk ratio model, a high-voltage cable failure probability model is established. The importance of the cable is characterized by a failure loss model that considers both economic and noneconomic factors. Based on the risk assessment model of high voltage cable systems, this paper selects relevant information of multiple high voltage cable lines, obtains the key parameters of the model, and gives a practical case analysis. The cable risk assessment model proposed in this article can provide a certain reference for asset condition assessment and strategy planning of high-voltage cables.t.","PeriodicalId":6767,"journal":{"name":"2020 IEEE 3rd International Conference on Automation, Electronics and Electrical Engineering (AUTEEE)","volume":"8 1","pages":"143-146"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89466068","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}
