GRNN has such advantages as simple design and perfect convergence etc, so it has been widely used for complex nonlinear sys tem modeling. After briefly introducing the structure and algorithm of GRNN, a new nonlinear system robust modeling method based on GRNN and uniform design is proposed. A numerical simulation example is given, and simulation results show that the proposed method can be applied to nonlinear system modeling successfully and has such advantages as stable prediction results and better robustness etc.
