Abstract

Un aparato y método de control predictivo de modelo para controlar la operacion de un proceso (34) que tiene una señal de entrada al proceso (Xk) y una señal de salida del proceso (Yk), el cual incluye determinar una señal de salida del proceso predicha (Yk+n+m+2) en una condicion de estado continuo futura de acuerdo con un modelo del proceso, determinar una señal de error de estado continuo de acuerdo con la diferencia entre la señal de salida del proceso predicha y una señal de punto establecido deseada (Ysp), y determinar un conjunto de señales de cambio de entrada al proceso futuras (x), requiere de la correccion del error de estado continuo estimado (e), mediante la provision de cuando menos una respuesta de un paso en la salida del proceso en un tiempo futuro. Entonces se aplica el siguiente cambio de entrada al proceso neto de acuerdo con la suma del primer elemento actualmente determinado del conjunto de señales de cambio de entrada al proceso futuras (s) sumadas con cualesquiera señales de cambio de entrada al proceso futuras que se calcularan previamente, para la siguiente señal de cambio de entrada al proceso que se calcule de acuerdo con este método. El modelo se expresa en forma de velocidad. Los parámetros de sintonizacion del proceso están disponibles para amortiguar el cambio de entrada al proceso neto, así como el primer elemento actualmente determinado del cambio de entrada al proceso con respecto a una señal de cambio de entrada al proceso que se calcule de acuerdo con el error de estado continuo dividido entre la ganancia del proceso de estado continuo.
