| Abstract: | A wavelet neural network(WNN) model of flux linkage characteristic based on measured magnetization curves is presented for switched reluctance motors(SRM).A flux linkage measuring installation is setup by using a digital signal processor(DSP).The magnetization curves at different rotor positions are obtained by calculating flux linkage using a discrete method on an upper level computer.Then,a feed-forward neural network(FFNN) model of flux linkage characteristic is proposed.The commonly used Mexican hat wav... |
