Abstract: | ![]() To improve the performances of nonlinear dynamic system, a multi-model wavelet network is proposed. And the structure of multi-model wavelet networks is introduced. The multi-model wavelet network is used to model and control nonlinear system and it is compared with single wavelet network in simulation experiment.The result shows the mean square of multi-model wavelet network is 0.158,and the mean square of single wavelet network is 0.374. It proves that the multi-model wavelet network has higher control precision, faster response speed and better control performances than single wavelet network. |
