【Abstract】 Realization of α order time delay inverse systems based on wavelet neural networks is investigated,and sufficient existing condition the WNN is presented. Based on the time frequency localization properties of wavelet, many unnecessary hidden nodes are eliminated in the initialization procedure. The efficiency of the WNN is verified by computer simulation results.更多还原
