Design and Implementation of Takagi-Sugeno Fuzzy Tracking Control for a DC-DC Buck Converter

This paper presents the design and implementation of a Takagi-Sugeno (T-S) fuzzy controller for a DC-DC buck converter using Arduino board. The proposed fuzzy controller is able to pilot the states of the buck converter to track a reference model. The T-S fuzzy model is employed, firstly, to represent exactly the dynamics of the nonlinear buck converter system, and then the considered controller is designed on the basis of a concept called Virtual Desired Variables (VDVs). In this case, a two-stage design procedure is developed: i) determine the reference model according to the desired output voltage, ii) determine the fuzzy controller gains by solving a set of Linear Matrix Inequalities (LMIs). A digital implementation of the proposed T-S fuzzy controller is carried out using the ATmega328P-based Microcontroller of the Arduino Uno board. Simulations and experimental results demonstrate the validity and effectiveness of the proposed control scheme

Regulación emocional y manejo de conflictos conyugales en mujeres de la Iglesia Adventista de la Unión Colombiana del Sur, 2017

El presente estudio tuvo como objetivo determinar la relación entre regulación emocional y el manejo de conflicto conyugales en mujeres de la Unión Colombiana del Sur de la Iglesia Adventista del Séptimo Día, Bogotá, 2017. Corresponde a un estudio correlacional de corte descriptivo no experimental, con una muestra de 520 mujeres casadas. Los instrumentos utilizados para comprobar la hipótesis fueron la dimensión regulación emocional del test de inteligencia emocional TMMS-24 de Extremera y Fernández-Berrocal (2005) y la escala de manejo de conflictos conyugales EEMC de Arnaldo (2001) en su versión de 34 ítems expuesta por Cienfuegos (2011). La regulación emocional posee una correlación positiva y altamente significativa con varias dimensiones de la escala de manejo de conflictos: “Reflexión y Comunicación” (rs = .399, p <.01), “Afecto” (rs = .332, p <.01), “Tiempo” (rs = .376, p <.01), “Automodificación” (rs = .372, p <.01) y “Acomodación” (rs = .276, p <.01). Se aprecia también que la regulación emocional presenta una correlación negativa y significativa con “Evitación” (rs = -.088, p <.05), aunque en un nivel correlacional bajo.TesisLIMAEscuela de Posgrado Unidad de PsicologíaPsicología positiv

Estrategia pedagógica basada en hábitos adecuados del uso del internet que puedan generar procesos de aprendizaje autónomo en estudiantes que cursan primer semestre de Psicología de la UNAD del CEAD Vélez.

Para este proyecto se hace un abordaje del aprendizaje autónomo unido a una estrategia pedagógica de implementación de hábitos adecuados sobre uso del internet, teniendo en cuenta que es la principal herramienta de construcción y evolución de este aprendizaje. Para esto se realiza una revisión bibliográfica donde se estudia desde la historia de la educación y de la tecnología hasta el punto donde estas se unen para facilitar la educación a nivel mundial y nacional. Abordando desde los primeros autores como Piaget, Ausubel, e investigadores, que plantearon las primeras teorías de la educación, hasta los que en principio hablaron sobre el aprendizaje autónomo y sus primeros estudios. Se ilustra la unión de la tecnología y medios de comunicación como el internet y demás herramientas de las Tecnologías de la Información y la Comunicación. También se profundiza sobre la efectividad del aprendizaje autónomo, sus beneficios y dificultades, al igual que su desarrollo y como este influye en el diario vivir.or this project an approach is taken to autonomous learning coupled with a pedagogical strategy of implementation of appropriate habits on internet use, taking into account that it is the main tool of construction and evolution of this learning. For this, a bibliographic review is carried out, where it is studied from the history of education and technology to the point where they unite to facilitate education at a global and national level. Approaching from the first authors like Piaget, Ausubel, and researchers, that raised the first theories of the education, to those who in principle talked about the autonomous learning and its first studies. It illustrates the union of technology and media such as the Internet and other tools of Information and Communication Technologies. It also explores the effectiveness of autonomous learning, its benefits and difficulties, as well as its development and how it influences the daily life. The chosen approach for this research is descriptive type. Since according to Hernández, Fernández and Baptista (2003) this research approach, It seeks to specify the properties, characteristics and profiles of individuals, groups, communities or any other phenomenon that is analyzed. To achieve the objective, a focus group was selected, with 14 students from the total population of psychology students from UNAD. The students involved initially responded to a virtual survey, which allowed them to obtain valuable information about their relationship and perception with the internet. Later, three workshops were held that sought to acquire and potentialize skills on the use of the internet and finally to know the degree Of utilization and satisfaction in relation to them, the impact assessment of the same was carried out
