Error Compensation Method for Temperature Control in Trace Water Analyzer Calibration Device

摘要

In this paper, false nearest adjacent points method will be used for error compensation of heating furnace in device for standard gas with trace water preparation. In different temperature difference between environment and heating furnace, phase space of nonlinear time series for temperature will be reconstructed, which can improve the sensitivity of the input data for NN and simplify the measurement model. Then nonlinear regression will be completed by RBF NN. So the temperature measurement model of heating furnace will be obtained. Experiment proves that the measurement error in this method is reduced greatly, also the influence of environment temperature is reduced. By the contrast experiment, the good performance of the FNN-RBFNN is verified.
