| Abstract: | The reason?that fluorescence lifetime of?optical fiber?fluorescence?temperature measuring system exists nonlinear?error is analyzed in this paper. In order to realize?error compensation?to improve the detection accuracy, the paper?adopts fuzzy?strategy for?nonlinear error compensation?of the fluorescence lifetime to eliminate the?influence of errors. Use simulation model?established by?MATLAB and test data?of actual system to?verify the experimental result, and it shows that?the fluorescence optical fiber temperature?measuring?system based on fuzzy strategy?can effectively improve the?stability and accuracy of?fluorescence lifetime. So the?research has important?significance for improving the accuracy and?robustness of the?fluorescence?optical fiber temperature measuring?system. |
