Induction machine faults detection using stator current parametric spectral estimation
We propose a new model order and spectral estimation technique to detect fault frequency signatures. The proposed technique is asymptotically optimal and exhibits high-resolution capabilities. We demonstrate the appropriateness of the approach on major faults in an induction machine. We prove the effectiveness of the proposed technique on simulated and experimental data.
