2050熱連軋壓力監(jiān)控模型的研究

寶鋼2050熱連軋張力觀測器模型中，采用了液壓監(jiān)控輥信號進行反饋控制，但是液壓監(jiān)控輥調(diào)節(jié)器設置不夠合理，使系統(tǒng)包含了張力差的誤差累積，造成了軋制過程中的拉鋼或起套問題。根據(jù)生產(chǎn)的工況條件，把張力監(jiān)控輥調(diào)節(jié)器設置為一階跟隨系統(tǒng)，大大改善了系統(tǒng)的穩(wěn)定性，有效地減少了起套和拉鋼問題的發(fā)生。

Abstract: In the 2050 hot-mill tension observer model, the hydraulic roller signals are employed for feedback control. However, the regulator design is not so reasonable that too many historical errors occur while the rolling process is going, which make the strip lap over or tension overload. Based on this process condition, the regulator was changed to a first order following system by selecting parameters. The system stability is greatly improved and the problems, strip lap over or tension overload, are reduced significantly.
