摘要：
The permanent magnet synchronous machines (PMSMs) have been used in a variety of different industrial applications. The transient parameters of the PMSM determine the safe operation and stability of the whole system. This paper introduces Hilbert-Huang transform (HHT) to identify the transient parameters of the PMSM. First of all, based on three-phase sudden short-circuit current, the DC and AC components from the transient current are extracted by using empirical mode decomposition (EMD). Then, by performing curve fitting on the envelope of DC and AC components separately, the transient parameters of the PMSM are obtained. Finally, the current waveform based on identification parameters is compared with the finite element (FE) current waveform to verify the effectiveness of the identification method.
