Ítem An academic design methodology for electrical mobility products - from necessity to functional prototype(2011-09-09) Osorio Gómez, Gilberto; Mejía Gutiérrez, Ricardo; Sierra Zuluaga, Luis Fernando; Universidad EAFIT. Departamento de Ingeniería de Diseño; Luis Fernando Sierra (lsierraz@eafit.edu.co); Ricardo Mejia (rmejiag@eafit.edu.co); Gilberto Osorio (gosoriog@eafit.edu.co); Ingeniería de Diseño - GRIDThe undergraduate program in Product Design Engineering at EAFIT University-Colombia, includes an applied project course during eight semesters with different topics -- Students attend their last project course in seventh and eighth semester integrated into one year topic -- In this project, they have to design a new high-tech consumer product in electrical mobility for different types of transportation need and to construct a completely functional prototype -- The objectives of these courses are to focus on the triad of “Product-User-Context” as well as to foster design, engineering, manufacturing, management and entrepreneurship skills -- In order to offer a systematic way of working, and to obtain better results, a systematic design methodology has been adopted, adapted and applied during the whole product development process in order to facilitate representation, analysis, calculation, management and control of the information related to the product -- The methodology is broadly explained through activities, tools, information and results related to four main stages: 1) Need research & problem statement, 2) Conceptual design, 3) Detailed design and 4) Prototype construction & testing -- A successful case study is presented following all the stages of the presented methodology for the development of an Electric Power-Assisted BicycleÍtem Acondicionamiento del motor para conversión a gas natural vehicular(Universidad EAFIT, 2010) Cardona Isaza, Carlos Andrés; Díaz Torres, Adalberto GabrielÍtem Construcción de un prototipo de una planta portátil para producción de bioetanol hidratado(Universidad EAFIT, 2009) Jaramillo Ruiz, Gustavo José; París Londoño, Luis SantiagoÍtem Estimation of combustion engine technical state by multidimensional analysis using SVD method(Inderscience Enterprises Ltd., 2013-01-01) Martinod, R.M.; Betancur, G.R.; Castañeda, L.F.; Kalaczynski, T.; Zóltowski, M.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)The changes of vibration estimators as a result of engine maladjustment, waste, damage or failure are the main idea of vibrodiagnostic investigation. Diagnostic investigations that use vibration to determine the technical state of combustion engines are very difficult. A limited set of proposed methods could have use in diagnostics. This paper presents a validation of research results of the use of the singular value decomposition (SVD) method. The research object is a combustion engine with power 55 kW at 830 rpm, which is feasible to obtain signals generated by vibration, as well as investigate the influence of the engine in the variation of the vibroacoustic data. Using the SVD method is possible to decide which symptom in the observation matrix is the best to recognise the technical state of combustion engines.

Departamento de Ingeniería de Producción; Ingeniería, Energía, Exergía y Sostenibilidad (IEXS)The hardware in the loop (HIL) platforms constitute an accelerated engineering design medium that subsequently reduces the risk of failure in the implementation process. This fact is enhanced when the designer is faced with extremely complex tasks and when design errors can lead to destructive and costly testing. The design of complex algorithms such as non-linear controllers applied to electronic control units of combustion engines, is a task of higher complexity level, and tests with incorrectly adjusted drivers can result in engine breakdown. This document reports the performance and effectiveness of a two-HIL scheme as an interactive design platform used for the design of electronic control units ECU, for internal combustion engines. The implementation and adjustment of two NMPC strategies aimed at optimizing the operation of the engine from three fronts: energetic, economic and environmental, involving independent and simultaneous objectives, give an account of the usefulness of the interactive design scheme. © 2017, Springer-Verlag France.Ítem NMPC controller applied to the operation of an internal combustion engine: formulation and solution of the optimization problem in real time(Springer-Verlag France, 2018-02-01) Chica, J.A.V.; Torres, A.G.D.; Acosta Maya, Diego Andres; Chica, J.A.V.; Torres, A.G.D.; Acosta Maya, Diego Andres; Universidad EAFIT. Departamento de Ingeniería de Producción; Ingeniería, Energía, Exergía y Sostenibilidad (IEXS)Numerical optimization solve problems efficiently where such efficiency is focused on the speed with which the optimal x* is achieved, is open line of research and strong work in the scientific community in order to achieve control systems in dynamic processes with response times of the order of milliseconds. A clear example of this, is the implementation of optimal controller’s combustion engines. For subsequent approach to the design and implementation of nonlinear model predictive control controllers, it has made a comparison of yields algorithms quadratic programming by active set with linearization restrictions, and sequential quadratic programming with single shooting technique to solve quadratic optimization problem formulation referred to a dynamic internal combustion engine of spark ignition, in embedded systems with real-time processing. © 2016, Springer-Verlag France.Ítem NMPC controller applied to the operation of an internal combustion engine: formulation and solution of the optimization problem in real time(Springer-Verlag France, 2018-02-01) Chica, J.A.V.; Torres, A.G.D.; Acosta Maya, Diego Andres; Universidad EAFIT.
