Abstract

UN ANGULO DE DETECTOR DE ROTACION TIENE UNA UNIDAD IMPULSORA QUE SUMINISTRA SEÑALES DESFASADAS DE 90 GRADOS A UN PAR DE BOBINAS DE ESTATOR Y MIDE UNA SALIDA ANALOGICA PROCEDENTE DE UNA BOBINA GIRATORIA QUE HAY EN UN RESOLUTOR. UN DISPOSITIVO CALCULADOR CALCULA EL ANGULO ROTACIONAL DEL RESOLUTOR UTILIZANDO LA SALIDA DE UN CONVERTIDOR ANALOGICO A DIGITAL QUE RECIBE LA SALIDA ANALOGICA DE LA PIEZA GIRATORIA. EN UNA PUESTA EN PRACTICA DE LA INVENCION, EL DISPOSITIVO CALCULADOR REALIZA UNA TRANSFORMADA DE FOURIER PARA CALCULAR LA FASE DE UN COMPONENTE DE FRECUENCIA FIJA QUE SE ENCUENTRA EN LA SALIDA DE LA BOBINA GIRATORIA. EN OTRA PUESTA EN PRACTICA DE LA INVENCION, LA UNIDAD IMPULSORA SUMINISTRA SEÑALES EN DONDE F(T/2 + T) =-F(T) Y EL DISPOSITIVO CALCULADOR REALIZA UNA TRANSFORMADA DE FOURIER UTILIZANDO LOS DATOS PROCEDENTES DE SEMIPERIODOS SUCESIVOS DE LA FORMA DE ONDA EXCITADORA. EN OTRA PUESTA EN PRACTICA DE LA INVENCION, LA SALIDA ROTORICA ES MUESTREADA A 1/4 DE PERIODO DE UNA SEÑAL DE EXCITACION PROCEDENTE DE LA UNIDAD IMPULSORA Y EL DISPOSITIVO CALCULADOR DETERMINA LA DIFERENCIA DE FASE ENTRE LA SEÑAL DE EXCITACION Y LA SALIDA ROTORICA. EN OTRA PUESTA EN PRACTICA MAS DE LA INVENCION, EL DISPOSITIVO CALCULADOR COMPARA LAS SALIDAS EN DOS O MAS PUNTOS QUE TIENEN UNA RELACION DE HORA FIJA Y COMPARA LOS RESULTADOS CON LOS DE LOS DATOS DE REFERENCIA ALMACENADOS PARA LLEGAR AL ANGULO DE ROTACION.
