Blind two-thermocouple sensor characterisation
نویسندگان
چکیده
Thermocouples are one of the most popular devices for temperature measurement in many mechatronic implementations. However, large wire diameters are required to withstand harsh environments and consequently the sensor bandwidth is reduced. This paper describes a novel algorithmic compensation technique based on blind deconvolution to address this loss of high frequency signal components using the outputs from two thermocouples. In particular, a cross-relation blind deconvolution for parameter estimation is proposed. A feature of this approach, unlike previous methods, is that no a priori assumption is made about the time constant ratio of the two thermocouples. The advantages, including small estimation variance, are highlighted using results from simulation studies.

On the stability and biasedness of the cross-relation blind thermocouple characterisation method
The in situ characterisation of thermocouple sensors is a challenging problem. Recently the authors introduced a novel blind characterisation technique based on the cross-relation method of blind identification that allows in situ characterisation of temperature measurement probes consisting of twothermocouple sensors with differing time constants. While the technique has a number of advantages...
