Book excerpt: En la presente tesis de Maestría en Ciencias con Especialidad en Automatización se desarrolla un sistema de control multivariable adaptivo predictivo aplicado a sistemas con dinámicas variantes en el tiempo. Hoy en día existen procesos en la industria que son controlados con controladores convencionales haciendo suposiciones de linealidad, invarianza en el tiempo e interacciones de una entrada una salida. Estas suposiciones dan lugar a una serie de consecuencias que para ciertos procesos pueden ser aceptables, pero no para otros. Es por esta razón que es necesario encontrar una forma de hacer frente a las características dinámicas complejas de muchos procesos donde las relaciones dinámicas son entre múltiples variables con comportamientos no lineales y/o variantes en el tiempo. Una forma de realizarlo es mediante el uso de controladores que se adapten en línea a los cambios que pueden existir en un proceso, ya sean de no linealidad o de varianza en el tiempo y que además puedan predecir el comportamiento de un proceso con el fin de tomar acciones de forma temprana. En el presente trabajo de tesis se realiza una investigación e implementación de un esquema de control multivariable adaptivo predictivo como alternativa de solución a los problemas de no linealidad, varianza en el tiempo e interacciones de múltiples variables presentes en los sistemas dinámicos. Así se presenta el desarrollo completo de un controlador multivariable adaptativo predictivo para procesos representados a través de un modelo ARIMAX (Auto-Regresivo con variable exógena). Se muestran simulaciones de desempeño del algoritmo para un sistema MIMO 3x2, en escenarios de prueba con ruido y sin ruido. Se establecen a partir de éstas, criterios de ajuste para controladores multivariables adaptivos predictivos y posteriormente se elaboran las conclusiones resultantes de la presente investigación.

Book excerpt: En este trabajo de investigación se desarrollaron dos controladores modulares con estrategia adaptativa – predictiva, uno para el caso de sistemas con una entrada – una salida (SISO por sus siglas en inglés “Single Input – Single Output”) y otro para el caso de sistemas con múltiples entradas – múltiples salidas (MIMO por sus siglas en inglés “Multiple Input – Multiple Output”). En el presente trabajo se exponen los conceptos básicos de la estrategia CAP para sistemas SISO y sistemas MIMO, haciendo énfasis en la implementación específica que se realizó. Se muestran los resultados obtenidos al implementar las estrategias en distintos procesos con diversas dinámicas de interés para un investigador en el área de control. Estos resultados están basados en distintas pruebas como cambios en referencia, dinámicas variantes en el tiempo, ruido en la señal de control y distintos horizontes de predicción. La finalidad central de este trabajo es de validar el desempeño del esquema de control multivariable propuesto, utilizando sistemas simulados en la plataforma AspenTech HYSYS como nuevo concepto de prueba, la cual permita representar modelos dinámicos de una forma más realista tomando en cuenta las diversas ecuaciones físicas, químicas y matemáticas que rigen su comportamiento.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introducción: La implementación de un modelo de control en una planta sencilla SISO es relativamente simple teniendo en cuenta que el sistema consta de una única entrada y una única salida, en los sistemas MIMO las variables a controlar son como mínimo 2 y cada una con una complejidad diferente dependiendo del tipo de tecnología que lo compone, el controlador debe de ser capaz de identificar los parámetros del sistema y sintonizarse con la planta para lograr la respuesta más eficaz e impedir que se salga de control por perturbaciones muy grandes. Los sistemas de control como rama de la ingeniería mecatronica son los factores diferenciadores de la mecatronica con la automatización y las demás áreas de la ingeniería, y el control de fenómenos inestables es un reto académico y profesional que aporta conocimientos, experiencias y logros al proceso educativo y así mismo seguramente serán implementados en la vida profesional con mayor facilidad y perfección. La complejidad de un sistema MIMO garantiza que todos los conocimientos en identificación y control de sistemas sean aplicados con la mayor exactitud posible de manera que se logre la estabilidad de las plantas intervenidas en todo momento. Así como la implementación de los métodos de control sobre un sistema son proyectos llenos de expectativa para los estudiantes, también lo son para los docentes y directores que guían con ahínco al alumno en el proceso investigativo, y constructivo entregándole satisfacción y dándole estatus académico al alumno, al docente y a toda la comunidad universitaria.

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade model predictive control (MPC), also referred to as receding horizon control or moving horizon control, has become the preferred control strategy for quite a number of industrial processes. There have been many significant advances in this area over the past years, one of the most important ones being its extension to nonlinear systems. This book gives an up-to-date assessment of the current state of the art in the new field of nonlinear model predictive control (NMPC). The main topic areas that appear to be of central importance for NMPC are covered, namely receding horizon control theory, modeling for NMPC, computational aspects of on-line optimization and application issues. The book consists of selected papers presented at the International Symposium on Nonlinear Model Predictive Control – Assessment and Future Directions, which took place from June 3 to 5, 1998, in Ascona, Switzerland. The book is geared towards researchers and practitioners in the area of control engineering and control theory. It is also suited for postgraduate students as the book contains several overview articles that give a tutorial introduction into the various aspects of nonlinear model predictive control, including systems theory, computations, modeling and applications.

This book was released on 2007-09-08 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thepastthree decadeshaveseenrapiddevelopmentin the areaofmodelpred- tive control with respect to both theoretical and application aspects. Over these 30 years, model predictive control for linear systems has been widely applied, especially in the area of process control. However, today’s applications often require driving the process over a wide region and close to the boundaries of - erability, while satisfying constraints and achieving near-optimal performance. Consequently, the application of linear control methods does not always lead to satisfactory performance, and here nonlinear methods must be employed. This is one of the reasons why nonlinear model predictive control (NMPC) has - joyed signi?cant attention over the past years,with a number of recent advances on both the theoretical and application frontier. Additionally, the widespread availability and steadily increasing power of today’s computers, as well as the development of specially tailored numerical solution methods for NMPC, bring thepracticalapplicabilityofNMPCwithinreachevenforveryfastsystems.This has led to a series of new, exciting developments, along with new challenges in the area of NMPC.

Available in PDF, EPUB and Kindle. Book excerpt: "The book contains an enormous amount of information — mathematical, bibliographical and historical — interwoven with some outstanding heuristic discussions." — Mathematical Reviews. In this massive graduate-level study, Emeritus Professor Edwards (Australian National University, Canberra) presents a balanced account of both the abstract theory and the applications of linear functional analysis. Written for readers with a basic knowledge of set theory, general topology, and vector spaces, the book includes an abundance of carefully chosen illustrative examples and excellent exercises at the end of each chapter. Beginning with a chapter of preliminaries on set theory and topology, Dr. Edwards then presents detailed, in-depth discussions of vector spaces and topological vector spaces, the Hahn-Banach theorem (including applications to potential theory, approximation theory, game theory, and other fields) and fixed-point theorems. Subsequent chapters focus on topological duals of certain spaces: radon measures, distribution and linear partial differential equations, open mapping and closed graph theorems, boundedness principles, duality theory, the theory of compact operators and the Krein-Milman theorem and its applications to commutative harmonic analysis. Clearly and concisely written, Dr. Edwards's book offers rewarding reading to mathematicians and physicists with an interest in the important field of functional analysis. Because of the broad scope of its coverage, this volume will be especially valuable to the reader with a basic knowledge of functional analysis who wishes to learn about parts of the subject other than his own specialties. A comprehensive 32-page bibliography supplies a rich source of references to the basic literature.

Download or read book End Of life Management written by International Renewable Energy Agency and published by . This book was released on 2016-06 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar photovoltaic (PV) deployment has grown at unprecedented rates since the early 2000s. As the global PV market increases, so will the volume of decommissioned PV panels, and large amounts of annual waste are anticipated by the early 2030s. Growing PV panel waste presents a new environmental challenge, but also unprecedented opportunities to create value and pursue new economic avenues.This report, prepared jointly by the International Renewable Energy Agency (IRENA) and the International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS), is the first-ever projection of PV panel waste volumes to 2050. It highlights that recycling or repurposing solar PV panels at the end of their roughly 30-year lifetime can unlock an estimated stock of 78 million tonnes of raw materials and other valuable components globally by 2050. If fully injected back into the economy, the value of the recovered material could exceed USD 15 billion by 2050.
