The wavelet neural networks is used to learn the unknown nonlinear system. Taking the wavelet neural networks as a predictive model of the system, the control signals are directly obtained by minimizing the deviation between the expected value and the output value of the predictive model. The simulation result shows that the proposed method can give good control performance.
