In the implementation process, a prototype reconfigurable Antenna Microstrip Type E was developed that guarantees signal propagation in 2.4 and 5.8 GHz. The jammer control stages in the drone were also designed, consisting of data acquisition cards, sensors detection photoelectric and wireless communication cards, allowing the operator to decide the exact moment to carry out the attack. In addition, a remote control has been implemented that allows the operator to know the physical position of the target with respect to the position of the attacking drone. Finally, the operational tests were carried out in two stages, in the laboratory, analyzing the spectrum generated by the jammer, and in the field, which includes jamming tests on a commercial drone. Thanks to the results obtained, the operation of the prototype that inhibits the video transmission of the attacked target was verified.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"1 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":"130613194","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 paper, the evolution over the years of UAVs is presented and, a classification is proposed based on different parameters, as well as the advantages and disadvantages of each type.

Coating the outer glass of solar cell with small layer of oil improves the value of sunlight absorbed by panel and accordingly the efficiency of the panels dramatically increases due to high transmissivity of some types of oils, especially vacuum oils. In this experiment, four types of oils are examined such as vacuum oil, engine oil, abro oil used as a mineral oils and sunflower oil examined as a natural oil. During the experiment, it has been observed the efficiency of the solar cell panels that have been coated with vacuum oil (labovac oil) increased by 11.28% compared to the efficiency of the same panel before coating. Similarly, coating the outer surface of solar panel with 1.5 mm layer of chlorophyll improves the efficiency by 4.17% as chlorophyll absorb a wide range of sunlight falling on surface of the photovoltaic panel and thus increase its efficiency.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"40 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":"114786657","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}

To describe the model, activity data from the ORs and waiting lists for the year 2017 is used (near 15,000 interventions, an initial waiting list of 6,500 patients, 15 ORs, 150 surgeons, four daily hourly periods and consideration of weekends] to model the operation of the system using statistical and probability techniques.

In this context, there are a number of changes that must be made to the network infrastructure, including Core Network (CN) and Radio AccessNetwork (RAN) to support these new applications. In this work we demonstrate the implementation of Quality of Service (QoS) control through the Software Defined Network (SDN) paradigm in an abstract (CN) infrastructure, with the objective of investigating the benefits of using SDN for new scenarios and challenges for 5G network.

In this research work, the boiler of a combined-cycle power plant is controlled using three control strategies, which are designed and compared, for the variables drum water level ($L$) and superheated steam pressure ($p_{s}$). A conventional PI controller is designed using the Lambda-tuning technique to obtain the optimal controller's gains. In addition, a fuzzy logic-based controller that considers the error and the error's rate-of-change is applied. Finally, a model predictive control (MPC) is applied, which objective function is to minimize the steady state error and the variation of the control actions, thus the fuel consumption is reduced. The controllers' performance is compared by analyzing maximum overshoot, settling time, steady-state error, and mainly fossil fuel consumption, which influences the operating cost. The results show a proper performance of the three control techniques. However, MPC control achieves a higher reduction of fuel consumption.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"135 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":"115809204","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 main reason for its adoption is the exible architecture and good performance attained with a predictive control scheme. One of the main issues with this approach is the variable switching frequency. Therefore this paper presents an implementation of PTC to overcome this issue. The method consists on the application of two active plus zero voltage vectors to generate a fixed number of switching commutations in the inverter legs during each sampling period. The dwell time for each of the voltage vectors are calculated in the optimization process of the predictive control. The scheme is validated simulation results, demonstrating the constant switching frequency operation whilst keeping the high dynamic torque and ux response.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"119 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":"133038413","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}
