Abstract

Un sistema controla un proceso de planta que incluye variables manipuladas (es decir, estados de entrada) y variables de control (es decir, estados de salida). El sistema incluye circuitos sensores para proporcionar medidas de las variables de control y una memoria para almacenar una constante de tiempo de correccion y límites superior e inferior para la menos una variable de control. Los limites superior e inferior están separados por una banda de valores dentro de la cual se considera aceptable una variable de control un procesador incluye datos que describen un modelo del proceso que relaciona costos de variables manipuladas con variables de control y que, al ocurrir la solucion, proporciona adicionalmente valores parecidos para la variable de control, la logica dentro del procesador responde a una funcion de valor de la variable de control que esta fuera de la banda de valores, para determinar variables manipuladas de costo mínimo que dan como resultado un retorno del valor predecido de la variable de control al interior de la banda de valores, Instrumentos de control dentro de la planta operan para alternar las variables manipuladas (y estos de entrada) de acuerdo con las señales provenientes del procesador.
