| Abstract: | In this paper theoretical analysis and identification experiments for the basis weight dynamic models of a paper machine are given. The available models are obtained by a method of combining physics with experiments. The design and results of the experiments are presented. There are very good agreements between the results of the identification experiments and the theoretical model. The obtained models have been successfully applied to the combined self-tuning control of the basis weight loop. |
