Esta obra introduce al lector en la utilización de variables de estado para la resolución de problemas de control, pero sin olvidar la representación externa del sistema. Desde esta perspectiva, no solo se aborda el control de sistemas lineales con múltiples actuaciones y salidas, sino que también se estudian problemas de control no lineal y de control óptimo. Su principal objetivo es que los lectores dispongan de una guía que les permita avanzar rápidamente en sus conocimientos sobre esta materia. En esta segunda edición revisada, se ha llevado a cabo una mejora tanto de la notación como de las explicaciones para hacer más comprensible el texto. Además, se han ampliado algunos ejercicios, se han reorganizado varias secciones y se han introducido nuevos contenidos para completar los temas tratados. 1. Modelado de sistemas para su control; 2. Identificación de procesos lineales; 3. Análisis de la representación interna de sistemas lineales; 4. Realimentación lineal del vector de estado; 5. Análisis de sistemas no lineales; 6. Estabilidad de procesos no lineales; 7. Técnicas de control no lineal; 8. Técnicas de optimización; 9.Técnicas de optimización; 10.Filtro de Kalman; Apéndice A.Linealización armónica; Apéndice B. Lógica borrosa; Apéndice C. Generación de ruido blanco.
El objetivo de este libro es presentar las metodologías y técnicas de control de los sistemas dinámicos. El estudio abarca tanto sistemas lineales, continuos y discretos, como sistemas no-lineales.
En este libro se presenta una base para el diseno de controladores, mediante retroalimentacion de la salida, para sistemas dinamicos lineales a parametros variantes. Esta estructurado en dos partes. La primera parte establece las bases fundamentales para el analisis de los sistemas dinamicos, desde los sistemas no lineales, sistemas lineales a tiempo variante, hasta los sistemas lineales a parametros variantes (LPV). Mediante aproximaciones, los sistemas no lineales se expresan como sistemas lineales variantes. La segunda parte esta dedicada a la construccion de los controladores robustos. Se trata la realimentacion estatica de la salida (SOF), partiendo de una introduccion a la realimentacion de estados. Luego, una realimentacion dinamica de la salida que se caracteriza como un diseno por SOF. Finalmente se expone una SOF extendida, al realimentarse la salida y su derivada, mediante una justificacion de esta tecnica.
Vibration is a phenomenon that we can perceive in many systems. Their effects are as diverse as the personal discomfort that can produce the unevenness of a road or the collapse of a building or a bridge during an earthquake. This book is a compendium of research works on vibration analysis and control. It goes through new methodologies that help us understand and mitigate this phenomenon. This book is divided into two sections. The first one is devoted to new advances on vibration analysis while the second part is a series of case studies that illustrate novel techniques on vibration control. The applications are varied and include areas such as vehicle suspension systems, wind turbines and civil engineering structures.
This book is devoted to new methods of control for complex dynamical systems and deals with nonlinear control systems having several degrees of freedom, subjected to unknown disturbances, and containing uncertain parameters. Various constraints are imposed on control inputs and state variables or their combinations. The book contains an introduction to the theory of optimal control and the theory of stability of motion, and also a description of some known methods based on these theories. Major attention is given to new methods of control developed by the authors over the last 15 years. Mechanical and electromechanical systems described by nonlinear Lagrange’s equations are considered. General methods are proposed for an effective construction of the required control, often in an explicit form. The book contains various techniques including the decomposition of nonlinear control systems with many degrees of freedom, piecewise linear feedback control based on Lyapunov’s functions, methods which elaborate and extend the approaches of the conventional control theory, optimal control, differential games, and the theory of stability. The distinctive feature of the methods developed in the book is that the c- trols obtained satisfy the imposed constraints and steer the dynamical system to a prescribed terminal state in ?nite time. Explicit upper estimates for the time of the process are given. In all cases, the control algorithms and the estimates obtained are strictly proven.
