The compensation of the thermocouples cold junction temperature variation errors using a neuro-fuzzy controller

摘要

The paper presents a new method to compensate errors due to temperature variation at cold junction of the thermocouples. The presented method is based on the realization of a neuro-fuzzy controller in order to get a quick error compensation model based on information related to the cold junction temperature variations. The model uses the experimentally obtained numerical values and has the advantage of fuzzy logic to process empirical signals, without using analytical mathematical models.
