Abstract

The problem of dynamic thermocouple compensation is considered. Taking into account the nonlinear dependency of the thermocouple time constant on fluid velocity, a thermocouple model and a time constant model are proposed successively for estimation of nonlinear thermocouple time constant. This technique is most suitable for measuring dynamic temperature because of the precise description of time constant. The improve scheme offers better compensation of the thermocouple response. The parameter estimation is performed using GTLS to cope with the noise present on the regressors and the output.
