Abstract: The PLS (partial least squares) and BP network were applied to establish the online iron loss prediction mathematical model of silicon steel. The results showed that PLS and BP network have higher fitting and prediction accuracy, and BP network has higher accuracy. The model can be applied to on-line prediction of iron loss of silicon steel and development of new grade silicon steel products.
