Abstract

Métodos y sistema para el recurso de emergencia de retroalimentación de bucle menor. Un aparato de ejemplo incluye una retroalimentación de bucle menor que tiene un primer modo y un segundo modo. El primer modo es para generar un primer valor usado para controlar un dispositivo de control de proceso en una operación normal. El segundo modo es para generar un segundo valor utilizado para controlar el dispositivo de control de proceso durante una condición de falla. El aparato incluye un controlador para la transición entre el primer modo y el segundo modo basado en la identificación de la condición de falla.
