Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : In this paper, we investigate the advantages and feasibility of motor control using very fast (in megahertz) switching in place of traditional amplifiers. We also propose integrated motion-control architecture based on discrete-event control approach to be implemented in digital logic at an equally high rate. A switching controller combines the current and motion feedback paths into a single loop. A model-based observer estimates the load torque. When compared to second-order controllers implemented with traditional amplifiers, the proposed design promises increased performance, better efficiency, and improved load estimation. Simple implementation makes concepts of switching control very attractive in motion-control systems like control of dc or ac servomotors. The control algorithm designed by the proposed approach can be easily implemented on field programmable gate array platforms.

Power engineering and motion control web laboratory / Rojko, Andreja in IEEE transactions on industrial electronics, Vol. 57 N° 10 (Octobre 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 10 (Octobre 2010) . - pp. 3343 - 3354 Titre : Power engineering and motion control web laboratory : design, implementation, and evaluation of mechatronics course Type de document : texte imprimé Auteurs : Rojko, Andreja, Auteur ; Hercog, Darko, Auteur ; Jezernik, Karel, Auteur Année de publication : 2011 Article en page(s) : pp. 3343 - 3354 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Distance education Engineering Mechatronics Motion control Power engineering Remote laboratories Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : During the E-learning Distance Interactive Practical Education project, 13 partners from 11 European countries joined together to build a power engineering and motion control remote laboratory, which would offer 18 complete online courses with remote experiments and high-quality documentation, to students from the universities of all participating partners. The major benefit of this project is the possibility of sharing expensive equipment and lessening the burdens of technical and organizational problems. This paper outlines the project's goals, organization, and, as an example, realization of one of the project's modules. The described module is a mechatronics motion control course, which explains the most important aspects of motion control design, from modeling, simulations, control design, experimental validation, and comparison between various controllers. The technical solutions, educational strategy, and realization details are given for the module. The pilot testing of the module was performed to assess the module and find out what the students' personal attitude concerning e-learning and remote experiments. The results of testing are presented and discussed.
