| Abstract: | Based on the combination of genetic algorithms and orthogonal optimum seeking method, along with the modification of the width of the radial basis function (RBF) a novel nonlinear dynamic system modeling approach is proposed to correctly determine the centers of the RBF. This approach has greatly improved the generalization and robustness of the RBF neural network. Simulation shows that the improved neural network has successfully modeled the continuous flow stirred tank reactor system. |
