用台劳级数分析的方法,给出了压力AGC系统的影响函数表,应用压力与辊缝的两种关系式,得到了压力AGC系统的动态控制模型通过电子计算机仿真实验,证明该控制模型是可以实用的。分析证明了AGC系统的增益因子用于恒张力控制系统的冷连轧机(或可逆式轧机)应当修正,本文推导出如下关系式 Using the method of stage series analysis, the influence function table of pressure AGC system is given. By using the two relations of pressure and roll gap, the dynamic control model of pressure AGC system is obtained. The computer simulation experiment shows that the control model It is practical. The analysis proves that the gain factor of AGC system is applied to the tandem cold rolling mill (or reversing rolling mill) of constant tension control system. This paper deduces the following relation
