摘　　要：通过对厚度、板形和张力这三个自动控制目标量的分析,表明可以用厚度实现最简单、最有效的控制。厚度的控制主要由负荷分配和AGC系统来实现的。厚度自动控制最好的方法是DAGC。无迭代计算的Φ函数负荷分配方法,不仅解决了静态负荷分配问题,同时动态调节值还可以补偿轧辊实时凸度变化。自动控制的另一个主要问题是测量,通过可测的压力、机械辊缝、张力(冷连轧)和活套角就可以完全满足对板带轧制中的全部目标量的有效控制。Through the analysis of the thickness,plate shape and tension these three automatic control target values,it shows that can use thickness control to realize the most simple and effective control. The thickness control is mainly realized by the load distribution and AGC system. The best method of the thickness automatic control is DAGC and no interactive calculation Φ function load distribution,not only solve the static load distribution problems,but also the dynamic adjusting value can compensate for real-time camber change of the roll. Another major problem of automatic control is measurement,through the measurement of pressure,mechanical roll gap,tension（ cold rolling mill） and a loop of angle,can completely realize effective control for all the targets of the strip rolling control.
