Abstract

Un método para operar un sistema de accionamiento hidráulico (10) durante una falla de sensor de presión es provisto. El sistema de accionamiento hidráulico (10) incluye una bomba (14), un depósito (12), un primer puerto de trabajo (32) y un segundo puerto de trabajo (34), un sistema de válvula con orificios individuales (22, 38, 46, 54), un sistema sensor de presión, y un controlador (56) para regular al sistema de accionamiento hidráulico (10) con base en demanda de flujo de fluidos y en diferencias de presión determinadas. El método incluye detectar una falla de un sensor de presión (22) para el primer puerto de trabajo (32), cerrar segundo y tercer orificios (22, 46), y regular la bomba (14) para generar flujo de fluido correspondiente a presión máxima generada por la bomba. El método también incluye asignar un valor para la diferencia entre presión de bomba y la presión del puerto de trabajo (32) sujeto que es equivalente a un valor dentro de un rango asequible para diferencia entre las dos presiones. Mas aun, el método incluye regular un primer orificio (22) y un cuarto orificio (54) en respuesta a la demanda de flujo de fluido.
