Abstract

The influence of the error of the gas temperature model in a self-tuning gas turbine gas temperature gauge with the model is analyzed. It is shown that the error of the model negatively affects the quality of the transient processes in the gas temperature gauge. A block diagram of a self-tuning gas temperature meter with a correction of the error in the gas temperature model is proposed. An algorithm for correcting the influence of the error of the reference model on the quality of the gas temperature meter is developed. Results of modeling reflecting the quality of calculating the gas temperature in transient regimes are presented. The study was carried out by mathematical modeling.
