Book excerpt: En este trabajo de tesis se implementó un controlador adaptativo predictivo modular y reconfigurable en una plataforma tecnológica de programación. Dichas características permiten aplicar el controlador en diversos sistemas o aplicaciones de control. La motivación de realizar este trabajo de tesis surge de la necesidad de tener sistemas de control que cada vez cumplan mejor los objetivos de control ya que los sistemas convencionales, como el PID, en ocasiones no cumplen con los estándares de calidad requeridos para las aplicaciones industriales. Además, con la teoría de control clásico avanzada y la llegada de la computadora como sistema digital surge la posibilidad de aplicar dicha teoría en sistemas discretos. Una de estas tecnologías relativamente nuevas es el control adaptativo predictivo experto. Dicha estrategia tiene fundamento en la estrategia de control predictivo pero incorpora la adaptación en línea del controlador y el conocimiento experto del sistema en el que se aplique el controlador. En el presente trabajo se exponen los conceptos básicos de esta estrategia de control haciendo énfasis en la implementación específica que se realizó. La implementación realizada se basa en el control adaptativo predictivo, pero se realizó una mejora al introducir el tiempo de retardo como parámetro del controlador. Aunque no se implementó el componente experto como parte del controlador, éste se desarrolló en una plataforma tecnológica que permitirá modificar el controlador en trabajos futuros. Posteriormente se muestra la implementación del controlador y su interfaz gráfica que permite configurar el controlador para diversas aplicaciones. Adicionalmente, se presentan al lector una serie de aplicaciones de control en simulación utilizando el controlador desarrollado mostrando algunas características importantes de su comportamiento ante la variación de los parámetros del controlador. El objetivo de estas pruebas no es mostrar que el control adaptativo predictivo experto es mejor que otras estrategias de control, pues éste tema en particular ya ha sido abordado en otros estudios de tesis, por ejemplo en [14]. Con éstas aplicaciones se valida la implementación modular y la mejora del algoritmo en su manejo del tiempo muerto. Las aplicaciones realizadas consisten en el control de un sistema de primer orden y de un sistema de fase no mínima con la estrategia de control adaptativo predictivo. También se introduce la aplicación del controlador desarrollado en una estrategia de control avanzado conocida como Cascada, permitiendo observar la ventaja de la modularidad del controlador. El trabajo desarrollado es innovador ya que permite la exploración de diversas estrategias de control tal como la estrategia cascada, pues permite la extensión en las aplicaciones al uso de dos o más controladores basados en la estrategia de control adaptativo predictivo.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. 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 2014-12-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: El objetivo principal de esta tesis está dirigido al diseño de una estrategia de control adaptativo-predictivo basada en redes neuronales para el control de sistemas no lineales. Con el objeto de realizar el control se emplea una red neuronal que ejerce de modelo de la planta y otra red que ejerce las labores de controlador. El ajuste de los parámetros de la primera se realiza fuera de línea, quedando fuera del marco de esta tesis su adaptación en línea y asumiendo que con la información adecuada se puede disponer de un correcto modelo. La red neuronal que ejerce de controlador en cambio se adapta en línea en base al funcionamiento que el lazo presenta. Para poder realizar esta adaptación se realiza una modificación del algoritmo de entrenamiento dentro de la estrategia adaptativo-predictiva presentada. Esta modificación hace uso de la información que proporciona la red neuronal identificadora, que además de la predicción del comportamiento del sistema proporciona las derivadas parciales de entrada/salida necesarias en el entrenamiento del controlador. Dentro de la estrategia y del algoritmo de entrenamiento se ha trabajado en la formalización de los aspectos de la estabilidad del lazo de control. Esta estrategia ha sido probada en varios casos de uso y presentada en diversos foros tanto nacionales como internacionales.

This book was released on 2002-02-20 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Professor Poul Harremoes Environmental engineering has been a discipline dominated by empirical approaches to engineering. Historically speaking, the development of urban drainage structures was very successful on the basis of pure empiricism. Just think of the impressive structures built by the Romans long before the discipline of hydraulics came into being. The fact is that the Romans did not know much about the theories of hydraulics, which were discovered as late as the mid-1800s. However, with the Renaissance came a new era. Astronomy (Galileos) and basic physics (Newton) started the scientific revolution and in the mid-1800s Navier and Stokes developed the application of Newtons laws to hydrodynamics, and later, St. Venant the first basic physics description of the motion of water in open channels. The combination of basic physical understanding of the phenomena involved in the flow of water in pipes and the experience gained by "trial and error", the engineering approach to urban drainage improved the design and performance of the engineering drainage infrastructure. However, due to the mathematical complications of the basic equations, solutions were available only to quite simple cases of practical significance until the introduction of new principles of calculation made possible by computers and their ability to crunch numbers. Now even intricate hydraulic phenomena can be simulated with a reasonable degree of confidence that the simulations are in agreement with performance in practice, if the models are adequately calibrated with sample performance data.

This book was released on 2018-12-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces three key issues: (i) development of a gradient-free method to enable multi-objective self-optimization; (ii) development of a reinforcement learning strategy to carry out self-learning and finally, (iii) experimental evaluation and validation in two micromachining processes (i.e., micro-milling and micro-drilling). The computational architecture (modular, network and reconfigurable for real-time monitoring and control) takes into account the analysis of different types of sensors, processing strategies and methodologies for extracting behavior patterns from representative process’ signals. The reconfiguration capability and portability of this architecture are supported by two major levels: the cognitive level (core) and the executive level (direct data exchange with the process). At the same time, the architecture includes different operating modes that interact with the process to be monitored and/or controlled. The cognitive level includes three fundamental modes such as modeling, optimization and learning, which are necessary for decision-making (in the form of control signals) and for the real-time experimental characterization of complex processes. In the specific case of the micromachining processes, a series of models based on linear regression, nonlinear regression and artificial intelligence techniques were obtained. On the other hand, the executive level has a constant interaction with the process to be monitored and/or controlled. This level receives the configuration and parameterization from the cognitive level to perform the desired monitoring and control tasks.

Available in PDF, EPUB and Kindle. Book excerpt: Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.
