Aplicación de RT-Linux en el control de motores de pasos. Parte I; Application of RT-Linux in the Control of Steps Mators. Part I

La idea fundamental de este art&iacute;culo es mostrar c&oacute;mo controlar un motor de paso empleando el puertoparalelo de una computadora, y demostrar la eficiencia temporal de las aplicaciones que se desarrollan ensistemas preparados para ejecutar tareas de precisi&oacute;n; aprovechar al m&aacute;ximo la capacidad de tiempo realestricto que brinda RT-Linux para el control de accionamientos el&eacute;ctricos. Se desarrolla un peque&ntilde;o softwareen lenguaje C que env&iacute;a las se&ntilde;ales al puerto paralelo en el tiempo necesario. Este software no est&aacute;dise&ntilde;ado con fines comerciales, solo permite realizar pruebas sobre el circuito de control dise&ntilde;ado paraeste prop&oacute;sito.&nbsp;&nbsp;The fundamental idea of this article is to control a steps motor using the parallel port of a computer anddemonstrate the temporary efficiency of the applications that are executed in prepared systems to executetasks of real time. To take advantage of to the maximum capacity of strict real time that RT-Linux offers usfor the control of electric workings. A small software is developed in language C that sent the signs to theparallel port in the necessary time. This software is not designed with commercial, only allows to carry outtests on the control circuit designed for this purpose.</p

Este trabajo complementa al presentado anteriormente: "Aplicaci&oacute;n de RT-Linux en el control de motoresde pasos. Primera parte", de manera que se puedan relacionar a las tareas de adquisici&oacute;n y control para laobtenci&oacute;n de un sistema lo m&aacute;s exacto posible. Las t&eacute;cnicas empleadas son las de tiempo real aprovechandolas posibilidades del microkernel RT-Linux y los software libres contenidos en sistemas Unix/Linux. Lasse&ntilde;ales se obtienen mediante un conversor AD y mostradas en pantalla empleando el Gnuplot.&nbsp;&nbsp;The work presented in this paper is a complement to the control and acquisition tasks which were explainedin "Application of RT-Linux in the Control of Steps Motors. First Part", so that those both real time taskscan be fully related in order to make the whole control system more accurate. The employed techniquesare those of Real Time Taking advantage of the possibilities of the micro kernel RT-Linux and the freesoftware distributed in the Unix/Linux operating systems. The signals are obtained by means of an ADconverter and are shown in screen using Gnuplot.</p
