The impulse elimination approach by output feedback control is addressed by combining the eigenstructure and the closed-loop system's finite eigenstructure. With a base in the desired eigenstructure, the gains controller's parametric formulations doing the closed-loop system impulse-free and assigning the finite eigenstructure are referred. The computational simulation result is provided to verify the effectiveness of the proposed method. This study presents an approach to partial eigenvalue assignment for the descriptor system where an algorithm is presented for calculated the output feedback matrix by the Sylvester equation. Sylvester equations present the theorems. Two algorithms are implemented using the Sylvester equation, and examples were presented with finally their conclusions.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"51 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":"115986253","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}

However, the grid- and motor-side converter require be equipped with FB cells. To reduce this requirement, this work proposes the use of Hybrid MMC converters. To further improve performance at very-low frequencies, it is proposed that the intermediate link, between the grid- and motor-side converter, be operated as AC link, instead of DC-link, but only at low speed. An AC link voltage having a relatively small amplitude and frequency, compared to nominal values of the motor, is sufficient to maintain the ripple as low as that of the nominal speed. Results shows that 50% and 25%, of the total number of cells in the grid- and motor-side converter, respectively, are required to be of the FB type. This may be a practical solution for medium power drives that require to operate at very-low frequencies without torque restrictions.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"30 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":"126738412","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 objective of the article is to present information regarding the use and acceptance of ER by students from rural establishments in the Región de Atacama; The work methodology used was proposed sequentially and divided into groups of activities: i) Hypothesis Approach, ii) Definition of Methodology and Assessment Instruments, iii) Development of ER Activities, iv) Documentation and v) Analysis of Results. The information obtained after the results shows that the efficient and effective use of ER depends to a great extent on the level of ownership that the participants present in this regard, quickly becoming accustomed to the robot, carrying out participatory interactions between peers and oriented towards learning and solving problems.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"122 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":"127475803","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}

Modeling is supported by Artificial Neural Networks methodology with Multi-Layer Perceptron architecture and Back-Propagation training algorithm. In a real case study, load profiles in the Brazilian electrical system, from September 2013 to August 2014, are compared with clustering models traditionally used in load profile characterization to peak-load pricing.

The productive method to collect the energy from the framework for the most part relies upon its interfacing hardware. It is important to portray and streamline the interfacing circuit for expanding the yield power. The circuit parameters such as duty cycle, switching frequency, inductance and load resistance have been portrayed and streamlined to improve the effectiveness of the overall system. A higher order Cuk Converter is proposed for integrating piezoelectric energy harvester (PEH) and energy storage elements or load directly. The circuit has been simulated using Matlab Simulink. The supply voltage of the piezoelectric transducer is an impulse force and the regulated output DC voltage is obtained as 1.3V from a single crystal (PZT-5A) and a total of 5.2V is obtained by cascading five crystals. The output voltage of the crystal stack is rectified and boosted using Cuk converter. The operating range of the system is increased by employing PI controller, Sliding mode controller and Hysteresis controller.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"18 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":"115769448","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}

This paper studies the frequency variation, the sag, and swells effect on power converter by using the two most used topologies, the power converter as rectifier and inverter with their respective first order and second order filters respectively. The results show the large effect on the power converters and therefore demonstrate the importance of considering the frequency on the control design, since the entire operating region is affected.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"153 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":"116305611","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}

Automatic recognition of plant diseases is essential to automatically detect disease symptoms as soon as they appear in the growing stage. This paper provides a proposed methodology for the analysis and detection of banana leaf diseases using digital image processing techniques. The results obtained show that the proposed system can successfully detect and classify two major banana leaf diseases: Black Sigatoka (BBS) and Bacterial Wilt (BBW).","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"143 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":"123243040","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}

This project has been carried out to facilitate the monitoring of the production of each sector of the agricultural cooperative APBOSMAM (Asociación de Productores de Banano Orgánico Sector el Monte y Anexos Mallaritos), which provided production data. In the development of this study, two production ratios have been considered for the analysis: “Plant population per hectare ratio” and “Pre-bagged bunches ratio” by each sector during a week.
