Abstract

SE PRESENTAN UN SISTEMA Y UN METODO DE CONTROL PARA UN SISTEMA DE TRANSMISION AUTOMATIZADO QUE INCLUYE UNA TRANSMISION MECANICA TIPO DIVISORA SEMIBLOQUEADA (12). CON EL CONTROL SE CONSIGUE UNA TECNICA PARA DETECTAR LAS FALLAS DE ACOPLAMIENTO EN LA SECCION AUXILIAR O LAS FALLAS DE ACOPLAMIENTO ENTRE LA SECCION AUXILIAR Y LA SECCION PRINCIPAL Y PARA QUE EL SISTEMA PUEDA FUNCIONAR EN UN MODO TOLERANTE A LAS FALLAS UNA VEZ DETECTADAS TALES FALLAS. EN UN ASPECTO DE LA INVENCION, LAS FALLAS DE ACOPLAMIENTO EN LA SECCION AUXILIAR (214) SE DETECTAN CUANDO SE VERIFICA QUE LA SECCION PRINCIPAL (212) ESTA ACOPLADA SEGUN UNA RELACION APROPIADA Y SE VERIFICA QUE LA TRANSMISION ESTA ACOPLADA SEGUN UNA RELACION (GR{SUB,N}) DISTINTA DE LA RELACION OBJETIVO (GR{SUB,T}). EN OTRO ASPECTO DE LA INVENCION, LAS FALLAS DE ACOPLAMIENTO SE DETECTAN CUANDO SE VERIFICA QUE UNA SECCION ESTA ACOPLADA CORRECTAMENTE Y LA TRANSMISION NO SE ACOPLA SEGUN UNA RELACION OBJETIVO TRAS UN PERIODO DE TIEMPO PREDETERMINADO.
