摘要： 在带钢轧制过程中,不同性质的多个厚度精度控制AGC系统同时存在,有可能在调节辊缝的方向上相互影响和干扰.理论证明,厚控系统的压力AGC和监控AGC在一定条件下存在相互独立的可能性.通过数学意义上的公式推导,针对AGC系统的实际控制流程,对某热轧机厚控系统的控制参数和结构的调整和改变,得以使此厚控系统实现控制意义上的解耦,并且经过理论推导和计算机仿真.结果表明,此厚控系统的压力AGC和监控AGC是相互独立的.

Abstract: The accuracy of final strip gauge on hot strip mill depends on what gauge control means are adopted at each stand. It is possible to introduce different kinds of automatic gauge control (AGC) systems in the mill to work simultaneously. If so, different AGC systems may impact on each other with mutual disturbance while adjusting the roll gap in position. Rolling-force AGC and monitoring AGC are independent of each other if some AGC system parameters were preset suitably. In order to implement a decoupling control, the parameters and structure of the AGC system on a hot rolling mill were modified. As a result, it was proved theoretically that the rolling-force AGC system and monitoring AGC system could be independent of each other by computer simulation and mathematic models, namely, decoupling control of these two AGC systems was realized in the true sense.
