Abstract

EL CONTROL EN LINEA DE UN PROCESO SE CONSIGUE POR MEDIO DE CALCULOS DE ALIMENTACION HACIA ADELANTE DE PUNTOS DE CONFIGURACION (SP) VARIABLES MANIPULADOS, MODIFICADOS DURANTE CADA UNO DE LOS FRECUENTES CICLOS DE OPTIMIZACION POR ESTADO DE RETROALIMENTACION (84) DETERMINADO POR EFECTOS REALES CONTRA PREDECIDOS DE CAMBIOS DE LOS PUNTOS DE CONFIGURACION EN LAS VARIABLES CONTROLADAS DEL PROCESO. VALORES DE PROCESO, ECONOMICOS, CONTRACTUALES, Y DE PARAMETROS DEL EQUIPAMIENTO SE OBTIENEN Y RECOGEN CONTINUAMENTE Y SE USAN PARA CALCULAR LOS PUNTOS DE CONFIGURACION OPTIMOS DE LAS VARIABLES MANIPULADAS ANTES DE QUE SE APLIQUE EL ESTADO DE RETROALIMENTACION (84). LOS FACTORES DE DESVIACION SE AÑADEN AL ESTADO DE RETROALIMENTACION (84) PARA PROPORCIONAR CALIBRACION EN LINEA DE INSTRUMENTOS DE MEDIDA CLAVES. LAS DESVIACIONES EN EL RENDIMIENTO DEL PROCESO (87) SE ACTUALIZAN EN LINEA PERIODICAMENTE POR MEDIO DE RUTINAS AUTO-EJECUTABLES (72, 85) CALCULADAS COMO FACTORES DE CALIBRACION PARA ECUACIONES DE PREDICCION (81) Y CONTROL (71) BASANDOSE EN RIGUROSAS SIMULACIONES DE PROCESOS Y RENDIMIENTOS DE FABRICAS REALES.
