In this paper, we present an anisotropic mesh adaptation scheme that optimizes the mesh regarding this preferential evolution which results in high spatial anisotropy in the gradient of the damage filed. This mesh adaptation is driven by an error indicator based on the interpolation error estimate to prescribe size, shape and orientation of elements by using a metric tensor, this metric is then used to generate the anisotropic adapted mesh thanks to the meshing software MTC. Numerical experiences show the effectiveness of this technique to capture the localization zones and to take into account the spatial anisotropy of the damage growth.","PeriodicalId":359089,"journal":{"name":"International Conference on Electronics, Control, Optimization and Computer Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127496966","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 critical to accurately identify these parameters. One technique, known as online parameter identification, in which parameters of the battery model are constantly updated can be implemented to solve this issue effectively. In this paper, we suggest a new algorithm AFFRLS (adaptive forgetting factor recursive least squares) to extract the parameter of the battery model, then to predict the output voltage, and compare it to the original RLS (recursive least squares). To assess these techniques, we used experimental data performed on the LG 18650HG2 Li-ion Battery. We supplied the data to the algorithms and compared the estimated output voltage for one dynamic profile named the urban dynamometer driving schedule UDDS. Results show that AFFRLS has low distribution in high error range up to 6.4% less than RLS, this means that AFFRLS has a better parameter identification.

As a result, the developed centroid algorithm plays an important role in the development of the sun sensor.Conventional digital sun sensor uses thresholding and filtering to extract sun vector. However, this method is susceptible to straylight and the albedo effect, which are two of the most common reasons of incorrect solar sensor readings. The thresholding method is not used here due to the difficulty of determining the best threshold for generating binary images. Instead, this study proposes that a black sun readout method be implemented onboard satellites where the black sun phenomena is caused by high illumination. The Black Sun method, which runs on the Raspberry Pi B+, is based on Template Matching, which uses the black spot as an indicator to locate the sun’s centroid. Despite the noise, the system extracts the sun centroid with more accuracy and reliability.","PeriodicalId":359089,"journal":{"name":"International Conference on Electronics, Control, Optimization and Computer Science","volume":"358 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115868738","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}
