Abstract

Un método para controlar la operacion termodinámica de una disposicion de enfriamiento para predecir una condicion de recalentamiento del compresorde dicha disposicion. El recalentamiento inminente del motor de compresor en un enfriador se predice comparando valores de salida medidos en el enfriadorcon valores de salida predichos pasando dichos valores de salida y valores de entrada de enfriador a través de un filtro Kalman. Las variaciones queexceden umbrales se utilizan para predecir la condicion de recalentamiento. El filtro Kalman se deriva de un modelo de espacio estado de orden inferiordel enfriador, cuyos valores de matriz se derivan por regresion lineal de las salidas y estados que resultan de la excitacion deentrada de senalaleatoria de un modelo de orden superior del enfriador en una computadora.
