| 英文摘要 |
| For the copper-converting process with significant variation in dynamics and limited information of process, we propose an intelligent integrated modeling method based on its limited data information. First, we develop a nonlinear reaction kinetic model for the copper-converting process by the metallurgical reaction principles; second, we create a model for optimizing its kinetic coefficients based on the limited data and by using the Runge-Kutta formula. Finally, by employing particle swarm optimization and pattern searches with the typical sample set generated by intelligent decision, we put forward a hybrid intelligent algorithm to acquire the optimal kinetic coefficients for the dynamic model of copper converting process. The maximum relative error is less than 5%, when comparing the simulation result of our dynamic model with the real value of the Peirce-Smith(PS) converter in a copper smeltery. This shows the effectiveness of the proposed model. |
