Abstract

DISPOSITIVO DE CONTROL NUMERICO PARA REGULAR LA VELOCIDAD DE ROTACION DE UN SERVOMOTOR UNIDO A TRAVES DE UN HUSILLO A UN ORGANO MOVIL.EL DISPOSITIVO (10) CONSTA DE UN MICROORDENADOR (11) QUE ENVIA, A UN GENERADOR DE IMPULSOS (12), LAS SEÑALES DE REGIMEN Y TENDION DE ALIMENTACION ORDENADOS. EL GENERADOR ENVIA UN TREN DE IMPULSOS A UN CONTADOR DIFERENCIAL (13) QUE CALCULA LA DIFERENCIA ENTRE ESTOS Y LOS REALIMENTADOS A TRAVES DE OTRO GENERADOR (21). LA DIFERENCIA SE INTRODUCE EN UN CONVERTIDOR DIGITAL ANALOGICO QUE GENERA UNA TENSION.
