Abstract
SISTEMA PARA CONTROLAR LA TEMPERATURA DEL VAPOR EN UNA CALDERA QUE USA UN CONTROLADOR DE REALIMENTACION DE TIEMPO DE RETARDO CONOCIDO COMO PREDICTOR SMITH PARA PROVEER LA REGULACION DEL CONTROL DE LOS PARAMETROS REALES DE LA CALDERA QUE CAMBIAN CON LA CARGA. MAS ESPECIFICAMENTE, UN PREDICTOR ALIMENTADO EN AVANCE (38) QUE PREESTABLECE UNA TEMPERATURA DE ENTRADA AL RECALENTADOR SECUNDARIO PREVISTA PARA UNA CARGA DE LA CALDERA, LA TEMPERATURA PREVISTA SE CORRIGE PARA LA DESVIACION DE LA VELOCIDAD DE ENCENDIDO, DESVIACION DEL FLUJO DE AIRE Y CONTROL DE LA TEMPERATURA DE RECALENTAMIENTO MEDIANTE LOS RESPECTIVOS MODIFICADORES (42, 44 Y 46), SE EFECTUA UNA CORRECCION FINAL MEDIANTE UN CONTROLADOR DE REALIMENTACION (50), Y UN CONTROLADOR DE CASCADA (48) RESPONDE A LA TEMPERATURA DE ENTRADA PARA DISPONER UN BUCLE RAPIDO DEL PROCESO QUE RESPONDA A LOS PUNTOS DE CONTROL DEL PROCESO INTERMEDIOS.
