In this paper, the incipient fault diagnosis problem is studied for traction motor sensor fault. The data used for the fault diagnosis is from sensors of the closed-loop traction motor system, in which the deviations between normal and bias faulty data are of 1 %∼5 % and between normal and gain faulty data are of 1%∼10%. Considering the non-stationary of the data, the Ensemble Empirical Mode Decomposition...
