Feedback And Feed Forward Agc In 4high Reversible Mill

prediction for manufacturing factors in a steel plate,(agc) in steel plate production. agc has been successfully applied to commercial rolling mill system to select required control values. usually, the conventional agc systems are based on proportional integral derivative (pid) controller [13] [15], a feedback-loop mechanism adjusting control val-ues to address target values. such pid controllers.hydraulic gap control of rolling mill based on self-tuning,the mechanical structure of a common, 4-high rolling mill is shown in fig. 1 . the basic flat rolling operation shown in fig. 2 is being used to produce qualified plate and strip products. as one of the most important functions of the basic automation of the rolling mill, the hydraulic gap control (hgc) is the inner loop of the automatic gauge.(pdf) feedback and feedforward: action logs and class,kindt, d. & murphey, t.

    p63, a p53 family member, plays pivotal roles in epidermal development, aging, and tumorigenesis. thus, understanding how p63 expression is controlled has biological and clinical importance. rbm24 is an rna-binding protein and shares a high sequence similarity with rbm38, a critical regulator of p63. in this study, we investigated whether rbm24 is capable of regulating p63 expression.
