Teaching, Analyzing, Designing and Interactively Simulating of Sliding Mode Control

This paper introduces an interactive methodology to analize, design, and simulate sliding model controllers for R2 linear systems. This paper reviews sliding mode basic concepts and design methodologies and describes an interactive tool which has been developed to support teaching in this field. The tool helps students by generating a nice graphical and interactive display of most relevant concepts. This fact can be used so that students build their own intuition about the role of different parameters in a sliding mode controller. Described application has been coded with Sysquake using an event-driven solver technique. The Sysquake allows using precise integration methods in real time and handling interactivity in a simple manner.Peer ReviewedPostprint (published version

A practical approach to adaptive sliding mode control

This paper is concerned with the development of a practical approach to the design of adaptive sliding mode controllers. The objective is to define an adaptive control law that presents some desired advantages such as non overestimation of the disturbance input, cancellation of the chattering phenomenon, zero overshooting response, avoid control saturation and simplicity of algorithm tuning. In this practical approach a solution is provided that uses both, adaptive sliding surfaces and adaptive control gains so the proposed controller is able to manage input disturbances with bounded derivatives.Agencia Estatal de Investigación | Ref.

The use of interactivity in the controller design: Loop shaping versus closed-loop shaping

Frequency domain is one of the most popular and powerful framework to design control system. Usually this procedure is done using the open-loop transfer function. In this work, it is explored the possibility to perform the controller design by closed-loop shaping. It is analyzed how graphical representation and interactivity can be used in this framework to help automatic control students during the learning process.Peer ReviewedPostprint (published version

An Interactive and comprehensive software tool to promote active learning in the Loop Shaping Control System design

The classical loop shaping is a design procedure that explicitly involves the shaping of the open loop transfer function L(s), within a desired frequency spectrum by manipulating the poles, zeros, and gain of the controller C(s). Interactive software tools have proven as, particularly, useful techniques with high impact on control education. This kind of interactive tools has demonstrated in the past that students learn in a much more active way. This paper presents the basic functionality of the linear control system design (LCSD), an interactive tool for analysis and design of linear control systems with special emphasis on the classical loop shaping design. The software tool is implemented in Sysquake, a MATLAB-like language with fast execution and excellent facilities for interactive graphics, and is delivered as a stand-alone executable that is readily accessible to students and instructors. Several design problems are used to illustrate the main features of the LCSD tool to perform classical loop shaping.Postprint (published version

MIMO-GPCIT. Herramienta Interactiva de Control Predictivo Generalizado para Sistemas Multivariables con Restricciones

[ES] Este trabajo presenta una herramienta interactiva que permite estudiar el control de sistemas multivariables haciendo uso de la técnica GPC (Generalized Predictive Control). Con ella es posible especificar interactivamente el modelo de la planta a controlar en forma de matriz de transferencia, modificar los distintos parámetros de control (factores de ponderación, horizontes de control, horizontes de predicción, etc.) e incorporar restricciones sobre las salidas y entradas del sistema (tanto físicas como de comportamiento). De esta forma el usuario puede observar la interrelación entre las distintas variables y visualizar de manera inmediata cómo, al realizar un cambio sobre algún determinado parámetro, el comportamiento del sistema se ve modificado.Los autores quieren agradecer a la CICYT la financiación de este trabajo en el marco delos proyectos DPI2001-1012, DPI2001-2380-C02-02 y DPI-2002-04375-C03-03.Guzmán, JL.; Berenguel, M.; Dormido Bencomo, S.

Study of fundamental control concepts through interactive learning objects

Information technology has contributed significantly to the renewal of teaching methodologies used in control systems teaching. Computer applications are becoming very popular as a support in traditional lectures and as self-learning tools. This paper describes an on-going project which tries to develop a suite of interactive learning objects composed by graphical interactive applications plus simple learning cards to cover the complete contents of an introductory control system course.Postprint (published version

Educación a distancia del profesorado de ciencias en el desarrollo de laboratorios virtuales

Two distance courses on the implementation of interactive virtual-labs are presented in this manuscript. Their audience is Science teachers who wish to make efficient use of interactive simulation in their classes. The first course, entitled “Laboratorios virtuales interactivos: un enfoque creativo para la enseñanza de las Ciencias en el aula y a través de Internet”, is part of the Continuing Education Program offered by UNED, the National Open University of Spain. The second course is a concise version of the first one. It is a free online course, written in English language, entitled “Virtual-lab implementation with Ejs”. This web-based course got the second award in the “Best Designed Course” competition of the 6th International Conference on Virtual University (December 2005, Bratislava, Slovak Republic). The simulation environment used to implement the virtual-labs is Easy Java Simulations (Ejs): a freeware, open source, Java-based tool conceived to be used by people with little programming skills. Online course website: http://www.euclides.dia.uned.es/simulab-pfp. Se presentan dos cursos a distancia, sobre el desarrollo de laboratorios virtuales interactivos, que están especialmente dirigidos a profesores de materias de Ciencias que deseen aplicar eficazmente la simulación interactiva por ordenador en sus clases. El primero de ellos, “Laboratorios virtuales interactivos: un enfoque creativo para la enseñanza de las Ciencias en el aula y a través de Internet”, pertenece al Programa de Formación del Profesorado de la UNED. El segundo curso, “Virtual-lab implementation with Ejs”, es una versión online gratuita del anterior y está escrito en lengua inglesa. Este curso ganó el segundo premio del concurso “Best Designed Course Award”, celebrado en 2005 con motivo de la 6th International Conference on Virtual University (Bratislava, Eslovaquia). El entorno de simulación empleado en ambos cursos es Easy Java Simulations (Ejs): una herramienta gratuita, de código abierto, especialmente concebida para ser usada por personas con escasos conocimientos de programación.
