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.

Download or read book Dise o e implementaci n de un controlador adaptativo predictivo modular y su aplicaci n en una estrategia avanzada de control written by Joel Castillo Gómez and published by . This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. 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 2012-12-14 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades, we have witnessed unprecedented innovations in the development of miniaturized electromechanical devices and low-power wireless communication making practical the embedding of networked computational devices into a rapidly widening range of material entities. This trend has enabled the coupling of physical objects and digital information into cyber-physical systems and it is widely expected to revolutionize the way resource computational consumption and provision will occur. Specifically, one of the core ingredients of this vision, the so-called Internet of Things (IoT), demands the provision of networked services to support interaction between conventional IT systems with both physical and artificial objects. In this way, IoT is seen as a combination of several emerging technologies, which enables the transformation of everyday objects into smart objects. It is also perceived as a paradigm that connects real world with digital world. The focus of this book is exactly on the novel collective and computational intelligence technologies that will be required to achieve this goal. While, one of the aims of this book is to discuss the progress made, it also prompts future directions on the utilization of inter-operable and cooperative next generation computational technologies, which supports the IoT approach, that being an advanced functioning towards an integrated collective intelligence approach for the benefit of various organizational settings.
Download or read book Control of Multiphase Machines and Drives written by Federico Barrero and published by MDPI. This book was released on 2020-01-24 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growing interest in electrical machines in recent times, the multiphase machine field has developed into a fascinating research area. Their intrinsic features (power splitting, better fault tolerance, or lower torque ripple) make them an appealing competitor to conventional three-phase machines. Multiphase electric drives have been recently used in applications where fault tolerance and continuous operation of the drive are required. However, the difficulties in extending the three-phase conventional current regulation and control structure to multiphase systems still limit their broad applicability in industry solutions. The main objective of this book is to illustrate new advances, developments, and applications in the field of multiphase machines and drives, while exposing these advances, developments, and applications to the scientific community and industry.

Available in PDF, EPUB and Kindle. Book excerpt: We make choices all the time - about trivial matters, about how to spend our money, about how to spend our time, about what to do with our lives. And we are also constantly judging the decisions other people make as rational or irrational. But what kind of criteria are we applying when we say that a choice is rational? What guides our own choices, especially in cases where we don't have complete information about the outcomes? What strategies should be applied in making decisions which affect a lot of people, as in the case of government policy? This book explores what it means to be rational in all these contexts. It introduces ideas from economics, philosophy, and other areas, showing how the theory applies to decisions in everyday life, and to particular situations such as gambling and the allocation of resources. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.
