Abstract

Un método para determinar un estimativo segmento-específico de un parámetro asociado con un bucle de control de proceso incluye recibir datos de la senal correspondiente a una senal a partir de un bucle de control de proceso, almacenar los datos de la senal, dividir los datos almacenados de la senal en una pluralidad de segmentos de datos y realizar un análisis estadístico en una primera pluralidad de segmentos de datos seleccionados a partir de una pluralidad de segmentos de datos para generar un primer estimativo segmento-específico del parámetro.
