Remote laboratory allowing full-range student-designed control algorithm

Abstract

The paper deals with the structure and the properties of a system implementing the remote laboratory, m the technical area, for university purposes. This system was intended for remote experiments on physical objects, but it allows virtual experimentation, too. The main contribution is the original software written for this laboratory, created by the authors and tested in the university. The key feature of the laboratory is that it allows the remote student to take full control of the equipment, in order to solve the didactical subject, protecting in the same time the laboratory against possible attacks. The described application is in the field of automatic control, hut remote experimentation in the field of electronics or other technical subjects is also possible. The student is allowed to collect data from the equipment, to reconfigure on-line the structure of the equipment and to write his own automatic control algorithm, without being limited to predefined algorithms. 0-7803-7596-3/02/$17.00 02002 IEEE

Sistema de Laboratorios a Distancia (SLD): laboratorio para la enseñanza del control automático a distancia

“…En general los laboratorios a distancia utilizan software ampliamente conocido como LabVIEW (TREVELYAN, 2002) y Matlab-Simulink (DIXON, et al, 2001, JUNGE, et al, 2000, pero tambiÈn algunos sistemas utilizan software especifico desarrollado para este fin, tal es el caso del sistema propuesto por Frangu y Chiculita en Frangu et al (2002), donde un proceso de control de nivel es presentado.Este artÌculo describe el diseÒo y construcciÛn de un laboratorio a distancia virtual y real enfocado al estudio del control autom•tico que ha sido desarrollado en la Universidad Central ìMarta Abreuî de las Villas. El SLD permite a los usuarios cambiar las referencias, modificar los par•metros de control, variar el tiempo de muestreo y diseÒar sus propios controladores de una forma sencilla, utilizando herramientas ampliamente conocidas en el •rea del control autom•tico como son Matlab y Simulink.…”
