[Abstract]:In order to improve the preparation process of nanometer iron powder and realize the accurate control of the temperature of nanometer iron powder decomposing furnace, a temperature prediction method of nanometer iron powder decomposing furnace based on Drosophila optimization algorithm and generalized regression neural network was proposed. In this method, the field data are collected, and the temperature of the temperature region is predicted by selecting the input liquid quantity and the opening factor of the heating device in each temperature zone. The temperature prediction model was established by generalized regression neural network, and the smoothing factor was dynamically optimized by Drosophila optimization algorithm. Different population sizes are selected to verify the model, and the prediction results of this model are compared with that of the generalized neural network model and particle swarm optimization model based on general generalized neural network (GNN) and particle swarm optimization (PSO). The results show that the average relative error of the model is 0.43 and the disturbance of artificial parameters can be eliminated. The model has good accuracy and stability and can be further used in the study of calciner temperature control.
