薄板连铸GA-LM-BP漏钢预报模型研究
Breakout Prediction in Thin Slab Continuous Casting Process Based on GA-LM-BP Neural Network
摘要
Abstract
Slow convergence and local optimal solution in the training process are two terrible drawbacks of the traditional BP neural network.The global optimization ability of genetic algorithm and the local optimization ability of LM algorithm were introduced into the training process of the BP neural network to improve its converge property,and then a GA-LM-BP neural network was established.The GA-LM-BP neural network model was trained and tested with the historical data collected trom a steel plant.The testing results show that the convergence rate of the GA-LM-BP neural network model is faster than the traditional BP neural network significantly.The generalization capability and the recognition accuracy for the temperature characteristics of the breakout prediction system are greatly improved after using GA-LM-BP neural network.关键词
