Using compensation algorithm of autoregressive distributed lag(ADL) model the errors of eddy current sensor were revised, and the measurement accuracy of eddy current sensor was improved. The characteristics of this method are low cost and effective. By comparison with multiple linear regression model, the advantages of autoregressive distributed lag model were verified in improving accuracy of eddy current sensor, and the engineering application of this method is better than that of multiple linear regression model.
