The study of decoupling control strategy for paper basis weight and moisture content

Aimed at the strong coupling between basis weight and moisture content in papermaking, this paper put forward a decoupling method based on neural network, which is realized by designing a computing network to offset coupling in the process, and makes generalized object´s transfer function matrix become diagonal. By decoupling control, we used slurry flow to control basis weight and steam flow to control moisture content successfully, and achieved good control effect. The actual operating results showed that this control algorithm can improve the profits of enterprises greatly and has some practical value.
