Abstract
In view of the problem that the reconstructed signal distortion and fixed deviation are easy to occur in the denoising process of the fault signal of the equipment power system,a new improved threshold denoising method is proposed.By constructing a new threshold function and a selection method improving the threshold,the advantages of soft and hard threshold denoising methods such as strong continuity,good smoothness and high degree of approximation are synthesized,the signal to noise ratio of the reconstructed signal is improved and the root mean square error of the reconstructed signal is reduced.The proposed denoising method is applied to the simulation test of the power system of unmanned aerial vehicle,and the results show that the denoising effects of this method are better,and there is certain feasibility and effectiveness.关键词
