【摘要】 介绍了某热连轧厂精轧机组AGC控制系统硬件配置,给出了AGC控制系统结构。针对现场的实际情况,引入了硬度厚度双前馈AGC、变塑性系数GM-AGC、带Smith预估器的监控AGC。为消除厚度控制对带钢张力造成的干扰,提出了秒流量补偿。实际应用表明,AGC效果明显,带钢全长上厚度偏差均可控制在80μm之内。更多还原

【Abstract】 In this paper the hardware configuration of the AGC control system of a hot strip mill is introduced, and the system structure of AGC is given.According to the practical situation of the mill,hardness and thickness feed-forward AGC,GM-AGC with variable ductility coefficient,and monitor AGC with Smith Predictor are introduced.Compensation for mass flow is applied to eliminate the interference of strip tension brought by AGC.Practical application shows that the effect of AGC is remarkable,and the range of gauge deviation along whole length of strips is lower than 80μm.更多还原
