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...
Wavelet analysis is used in parameters identification in this paper, because of the time frequency location characteristic and multi-scale ability of wavelet transform and multi-resolution analysis. Then this paper compares the neural network with wavelet transform to identify the direct thrust control system parameters, and obtains the results are shown that the wavelet transform is further suitable...
Wavelet analysis is used in direct thrust control system of linear motor drive in this paper. The change of the primary resistance of linear motor will greatly affect the performances of direct thrust control system at low speeds. The observation of flux linkage is improved by accurate identification of primary resistance, and the direct thrust control performance of linear motor is further improved...
To solve the effect of primary resistance change of the low-speed performance in direct thrust control system of linear motor. Wavelet analysis is used in primary resistance identification in this paper, because of the time frequency location characteristic and multi-scale ability of wavelet transform and multi-resolution analysis. Then wavelet transform research on direct thrust control system is...
