ponencia en congreso.listelement.badge 7-Level asymmetric multilevel current source inverter with predictive control(2018-01) Cossutta, Pablo; Aguirre, Miguel Pablo; Muñoz, Javier; Rivera, Marco; Melín, Pedro; Rohten, Jaime"In this paper a 7-Level Asymmetric Multilevel Current Source Inverter is presented. The topology considers two Current Source Inverters that follow a 1:2 ratio to generate the multilevel current waveform. A Model Predictive Control is used to track the internal current and voltage references as well as to keep the asymmetric ratio between the DC currents even during transient conditions. To properly use the predictive algorithm, the modelling equations of the presented topology are systematically obtained in continuous and discrete time domains, considering the characteristic constraints of a Current Source Inverter. Simulated dynamic tests are presented in order to prove the feasibility of the asymmetric approach and the properness of the predictive control technique."ponencia en congreso.listelement.badge Predictive control of a 27-level asymmetric multilevel current source inverter(2018-10) Muñoz, Javier; Soto, Bairon; Villalón, Ariel; Rivera, Marco; Cossutta, Pablo; Aguirre, Miguel Pablo"In this work a study of a 27-level asymmetric multilevel current source inverter is developed. The presented structure is composed by three current source inverters that together are in a 9:3:1 ratio to produce a current waveform with multiple levels. A model predictive control scheme is developed for tracking the references for the output AC voltages, and to keep the asymmetric ratio between the DC currents even during transient conditions. Furthermore, an extra control goal is included in order to reduce the commutations of the inverter, and therefore reduce the power losses. In order to apply the predictive controller, the equations of the model to be analyzed are obtained systematically for continuous and discrete time domains. Simulations are carried out to validate the proposal and the integrity of the predictive control strategy."proyecto final de grado.listelement.badge Proyecto de automatización de una cervecería artesanal(2012) Martí, Matías; Rodríguez, Leandro; Pingitore, Ricardo Alejandro; Amat, Alfonso Ignacio; Muñoz, Claudio"El presente trabajo describe el diseño, desarrollo y puesta en marcha del prototipo de un proyecto electrónico. En este caso, se trata de un aparato capaz de controlar bombas, válvulas, motores, etc. que permitirán automatizar una planta productora de cerveza artesanal, tanto a nivel casero como para el caso de una Pyme. Se trata de buscar una solución a la problemática que implica el tiempo elevado que el maestro cervecero debe dedicar a la hora de elaborar una tanda (o batch) de cerveza. El sistema tiene una alta capacidad de adaptación para distintas instalaciones productivas disponibles, con diferentes capacidades (desde 20 litros hasta varios cientos de litros por batch). Se logró la implementación de una planta productora automatizada, a partir de elementos disponibles, con la que se elaboró una tanda de 50 litros de cerveza. De esta forma, pudo validarse correctamente el prototipo construido, con resultados muy buenos."
