| Abstract: | Global optimization to the initial parameters of the wavelet neural network is made by improving the basic wavelet neural network replacing the traditional gradient method with the genetic algorithms.The improved wavelet network is applied to the motor fault diagnosis,and five groups of motor fault are authenticated.The experiment shows fast convergence and high computation accuracy of the algorithm,and it confirm the correctness and effectiveness of the method used in motor fault diagnosis. |
