| Abstract: | A novel near infrared spectroscopy method for measuring the composition of chemical products is proposed.It is based on near infrared spectroscopy method and adaptive neural network internal model control.The feasibility of the method is discussed.The adaptive neural network calibration model is tested by using the experimental data of straight-run diesel,hydrofining diesel and catalytic cracking diesel as training samples.It is shown that the method has high response speed,little error and good robustness,and the mean squared error(MSE)of calibration samples and predicted samples is all the order of 10-6 in the spectral range of 800～2 300 nm. |
