| Abstract: | Based on summarizing of the application of onhogonal method, an onhogonal method for deciding the number of hidden layers, neurons and the training step of neural networks is presented. Further, the networks are applied to describe the nonlinear relations of k1, k2, k3, P and onsite operating conditions in a soft measurement hybrid model of polyacrylonitrile. Then the quality performances are estimated online. The results of simulation show that this method is effective. |
