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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a simple and didactic account of the developments and practical applications of predictive, adaptive predictive, and optimized adaptive control from a perspective of stability, including the latest methodology of adaptive predictive expert (ADEX) control. ADEX Optimized Adaptive Control Systems is divided into six parts, with exercises and real-time simulations provided for the reader as appropriate. The text begins with the conceptual and intuitive knowledge of the technology and derives the stability conditions to be verified by the driver block and the adaptive mechanism of the optimized adaptive controller to guaranty the desired control performance. The second and third parts present strategic considerations of predictive control and related adaptive systems necessary for the proper design of driver block and adaptive mechanism and thence their technical realization. The authors then proceed to detail the stability theory that supports predictive, adaptive predictive and optimized adaptive control methodologies. Benchmark applications of these methodologies (distillation column and pulp-factory bleaching plant) are treated next with a focus on practical implementation issues. The final part of the book describes ADEX platforms and illustrates their use in the design and implementation of optimized adaptive control systems to three different challenging-to-control industrial processes: waste-water treatment; sulfur recovery; and temperature control of superheated steam in coal-fired power generation. The presentation is completed by a number of appendices containing technical background associated with the main text including a manual for the ADEX COP platform developed by the first author to exploit the capabilities of adaptive predictive control in real plants. ADEX Optimized Adaptive Control Systems provides practicing process control engineers with a multivariable optimal control solution which is adaptive and resistant to perturbation and the effects of noise. Its pedagogical features also facilitate its use as a teaching tool for formal university and Internet-based open-education-type graduate courses in practical optimal adaptive control and for self-study.

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 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 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.
