So, the existent contingencies to such case are tripping-method from grid, robust DC-Link with higher capacitors and additional power electronic hardware. Nevertheless, they comprehend a common drawback for being costly in the industry. Therefore, the Power Loss Ride Through behaviour on variable-speed drives is an important feature which is a worst-case where the system can suffer dips near to 99% on grid. Recently, Modular Multilevel Cascade Converters have been applied in Variable-Speed Drives applications due to their capability to operate at high-power rates and features such as enhanced fault-ride through capability during critical dip voltage (e.g., 99% of amplitude) in grid. Therefore, this paper presents a control strategy based on a transition mechanism between outer control loops on the nested control of a Modular Multilevel Matrix Converter drive with the aim to improve the Power Loss Ride-Through performance through keeping the energy store station uniform and stable. Simulation results obtained using PLECS software are presented to validate the effectiveness of the proposed control strategy.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116740620","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 way, mass spectrometry is combined with data mining techniques to produce fast, efficient, and low-cost pathogen detection. An automated desktop platform named X-MassFP is proposed to analyze and train predictive machine learning models capable of identifying pathogens based on m/z data from mass spectra. Previous research analyzed serum samples from healthy and diseased salmonid fishes with Piscirickettsia salmonis. Their spectra were obtained and used them to perform a multiple alignment and binning experiments with our platform. Then, many combinations of pipes were implemented to obtain the best predictive models. Different bin sizes and feature selectors were implemented, as well as the use of oversampling on unbalanced data sets. The best results obtained with the X-MassFP platform corresponded to KNN using multiple alignment and SVM using the binning method, with 90% and 88.8% of accuracy, respectively.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129568562","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 analyses are focused on the performance of the control scheme for feeding a local load. Three levels of control are proposed. Primary control is directly applied to power converters to manage the energy flow based on the reference current tracking. The secondary control oversees regulating the DC Bus voltage by means of the power balance, which ensures that the load power is equal to the power in the DC Bus. The tertiary control is in charge of the system dynamics, that is, it is responsible for responding adequately to sudden changes, in this case, when the load power increase. The primary control includes an input-output linearization control, allowing the use of linear controllers that are not limited to an operating point. A Maximum Power Point Tracking algorithm based on the incremental conductance is implemented on the photovoltaic panel. A suitable control scheme for the hybrid energy storage system is proposed to tracking both, DC link voltaje and AC output voltaje-current, alowing to stabilize the system to sudden changes. Simulated results are presented to validate the properness of the proposed control strategy.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130343435","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}
