This paper deals with fault detection and isolation (FDI) in sensors applied to a concentric-
pipe counter-flow heat exchanger. The proposed FDI is based on the analytical redundancy …

One of the major challenges in instrumentation is to identify wrong data (signal)
measurements and perform their validation. This can be done by regularly ensuring a …

In this paper, a method for monitoring the performance degradation in a heat exchanger is
presented. This method is based on the use of an adaptive observer which estimates the …

The goal of this work is to provide a method for monitoring performance degradation in
counter-flow double-pipe heat exchangers. The overall heat transfer coefficient is estimated …

This work presents a sensor fault compensation system, applied to a heat pump's helical
evaporator. The mathematical model of the evaporator is given by algebraic and differential …

This work deals with the problem of controlling the outlet temperature of a tubular heat
exchanger system by means of flow pressure. The usual industrial case is to try to control the …

This paper addresses temperature control of an engine bleed air system, as used on typical
aircraft, with a control strategy aimed at reducing ram air usage while maintaining fast …

Crossflow heat exchangers play a significant role in the operation of an aircraft's
environmental control system (ECS). The bleed air supplied by an aircraft engine, at high …

This paper investigates temperature control of an aircraft engine bleed air system, aiming at
reducing ram air usage to reduce fuel consumption while maintaining fast temperature …

The purpose of this paper is to deal with a novel intelligent predictive control scheme using
the multiple models strategy with its application to an industrial tubular heat exchanger …
