【Abstract】 Hot strip coiling temperature is one of the important parameters of performance index in hot rolled strip, and its control systems of highly nonlinearity. The coiling temperature of hot rolled strip is exactly predicted based on neural network (NN) and an improved BP algorithm.A new coiling temperature system based on NN combined with mathematical model was presented,where the feed-forward control was based on the NN and the feed-backward control was based on mathematic model. Finally, the prediction by the NN shows that the control performance is satisfactory, and it can make mathematical model of coiling temperature identified.更多还原
