| Abstract: | The three layer neural network model of hydrocyclones was created by BP method of MATLAB package, and the method of determining hidden layer cell number was put forward. By choosing calculation function sets and neural network structure, the prediction performance model for 14-20-2 was gotten by training the network from 60 sets collection appropriate teaching data. The result showed that the network could achieve higher precision. Based on the above, the performance of hydrocyclones was simulated by obtaining weight and bias value, the result showed that the created network structure can satisfy engineering demands. |
