Wavelet transform applied in analyze the end-effect of linear motor

To improve the end-effect influence, which is a main reason of influence on the characteristic of linear motor, wavelet analysis is used in study the end-effect of linear motor in this paper. Traditional analysis method is based on the Fourier transform, but it analyzes the non-stable signal will be usually lost some messages. Because of the time frequency location characteristic of wavelet transform. Then wavelet transform research on end-effect analysis of linear motor is proposed. This paper compares the Fourier transform with wavelet transform to analyze the end-effect, the results are shown that the wavelet transform is further suitable for improve the end-effect influence of linear motor. Then it makes the control system of linear motor have good performances.
