    En la actualidad los motores trifásicos poseen una gran predominancia dentro de la industria de la electrónica teniendo en cuenta que dependen de una frecuencia y un voltaje variables de gran potencia, viendo la necesidad de poder mantener la velocidad controlada, se usa lo que es el PWM (Modulación por Ancho de Pulso) pero en este caso para motores trifásicos el PWM basado en vector espacial (SVPWM). Una vez teniendo el SVPWM, se podría incluso ir más lejos se podría modelar todo un sistema donde a través del control digital se pueda a llegar a ser más precisos respecto a la velocidad controlada sin dañar el actuador al largo plazo, pudiéndose usar un control PID, Adaptativo, Fuzzy, etc. Teniendo en cuenta que toda esta etapa del control será implementada dentro de un microcontrolador este tendrá la suficiente capacidad de cómputo para ejecutar en tiempo real, debido a que internamente se ha implementado un RTOS (Real-Time Operating System) que en este caso es el FREERTOS

    The public lighting poles are part of the public lighting system, so its operation is important and is offered as a welfare mechanism for citizens, it has the disadvantage of the high cost of operation because it is in operation all night for 365 days of the year, in this work a low-cost system is designed to be able to supply power to the public lighting poles, based on a solar panel system and with sensors to be able to measure luminosity, voltages and current, this system sends the information to a base station using the XBEE protocol and viewed using LABVIEW software.Campus At

    Diseño de control no lineal por modo deslizante para regular el nivel del proceso tanque con agua, Callao 2021

    El presente proyecto de tesis doctoral nace en los procesos industriales, los líquidos son generalmente bombeados y almacenados en tanques para realizar tratamientos químicos o mezclas. Por ejemplo, en una refinería de petróleo, un desbordamiento de este líquido es peligroso y costoso, un depósito vacío da lugar a que las bombas o el sistema de drenaje operen sin líquidos; otro caso a considerar es un sistema de control de agua de alimentación de un reactor, el cual debe mantener un adecuado nivel de agua en la vasija del reactor para mantener un balance de refrigerante, mantener cubierto de agua el núcleo del reactor y mantener una eficiencia óptima de los separadores de vapor, si no se cumple con los requerimientos, el sistema incurre en daños. Para lidiar con los problemas antes mencionados, el controlador no lineal por modo deslizante es propuesto para establecer una performance de solución al problema del control de nivel de un tanque de agua. La variable a controlar es el nivel de agua. El sistema de control debe ser capaz de hacer que las variables controladas sigan la evolución de las consignas de referencia arbitrarias con mínimo sobre impulso, mínimo tiempo de estabilización y error en estado estable nulo consideraciones importantes para llevar a cabo una alta performance del sistema de control propuesto

    Virtual power plant for energy management: Science mapping approach

    No full text
    A bibliometric analysis was conducted to examine the trends and developments in the field of Virtual Power Plants (VPPs) from 2000 to June 2022. The selection and identification of data involved a systematic search resulting in 1245 articles for bibliometric analysis after applying the inclusion and exclusion criteria. Strategic diagrams, overlay graphs, and evolution maps were used to analyze the trends and themes in different periods. The analysis reveals the emergence and evolution of various themes and their interconnections. In the early periods, the focus was on energy market issues, distributed generation, and the control of Distributed Energy Resources. Themes such as microgrids, renewable energy, electric vehicles, and economic analysis have gained prominence over time. The present study also identified the introduction of new concepts such as prosumers, collaborative networks, and dynamic power plants in later periods. The performance analysis for the last period (2022) highlighted the centrality and density of themes such as power plants, renewable power plants, battery energy storage systems, and robust optimization. These themes are considered both fundamental and transverse in the research field. This study discusses the importance of VPPs and battery energy storage systems in addressing grid intermittency issues and providing auxiliary market services. The analysis also emphasized the management of the demand side and the integration of electric vehicles and Building Energy Management Systems in VPPs. Therefore, future directions for VPP research include innovative structures and topologies, big-data analysis, and diversified optimization techniques. This study provides insights into the evolution and current state of research in the field of VPPs and identifies areas for further exploration and development

    Dental procedures are very traumatic procedures in children, due to the fact of the trauma and pain that they are afraid of, children normally suffer during visits to the dentist, in this work the power to eliminate these fears through virtual reality is evaluated, Immersing the children in a setting that is comfortable for them, a measurement of brain activity is accompanied by the study through the measurement of the concentration that the child has, at the time of the dental procedure, which is subjected to a visual experience, the results indicate that the child is concentrating on the visual experience rather than the medical procedure
