Abstract

SE DESCRIBE UN SISTEMA DE MEDICION DE ANGULO DE GIRO, EN EL CUAL POR MEDIO DE UNA DETECCION OPTOELECTRONICA DE UN DISCO CON CODIGO, SE OBTIENEN CUATRO PARES DE SEÑALES ANALOGICAS, A SABER; 1, 8, 64 Y 512 SEÑALES DE SENO Y DE COSENO POR REVOLUCION. A PARTIR DE LOS PARES DE SEÑALES DE SENO Y DE COSENO SE FORMA EN UNA ELECTRONICA DE VALORACION LA TANGENTE DEL ARCO QUE REPRESENTA EL ANGULO. LOS ANGULOS DE LOS DIFERENTES PARES DE SEÑALES SE CONDUCEN JUNTOS A UNA PALABRA DIGITAL QUE REPRESENTA LA POSICION ABSOLUTA DEL ANGULO. LAS SEÑALES DEL SENO Y DEL COSENO DE LA DIVISION MAS PRECISA CON 512 PERIODOS POR REVOLUCION, SE EMPLEAN ADICIONALMENTE PARA EL RECUENTO INCREMENTAL DEL ANGULO, PARA LO CUAL SE AUMENTA LA RESOLUCION POR UNA INTERPOLACION DE LAS SEÑALES ANALOGICAS. POR CONSIGUIENTE, EL SISTEMA DE MEDICION DE ANGULO DE GIRO, ADICIONALMENTE A UNA MEDICION INCREMENTAL DEL ANGULO, PONE A DISPOSICION EN TODO MOMENTO TAMBIEN LA POSICION ABSOLUTA DEL ANGULO COMO PALABRA DIGITAL.
