摘要
Abstract
Because of the application of the non - linear electrical equipment, aircraft power system contains a number of harmonic components and inter - harmonics components. Aiming at the situation that the Fourier transform and wavelet transform method can not effectively carry out these harmonic signal extraction and analysis, the paper made use of Hilbert - Huang Transform ( HHT) extraction and analysis of the harmonics component for aircraft power system. Meanwhile, in order to solve the questions of overshoots,undershoots and the end swings existing during empirical mode decomposition (EMD) , it made use of cubic hermite polynomial interpolation for envelopes fitting instead of cubic spline interpolation extraction the envelope curve and the advantages of semi - periodical - semi - symmetrical method extending the signal boundary. The result of simulation shows that Hilbert - Huang transform can effectively extract and analyze harmonic component for aircraft power system.关键词
