摘　　要：在轧钢生产中,调整液压压下是钢带厚度控制的关键。具体分析研究了流量AGC(厚度自动控制)理论的控制模型,结合具体项目,给出了算法设计方案和关键参数的计算,同时给出了控制模型的功能模块图。根据现场的调试,将监控AGC引入其中作为算法的改进,从理论上给出了组合控制方案的数学表达式,画出了改进后的功能模块图。In mill roll, the key of thickness control is hydraulic down adjustment. The control model of mass flow AGC was analyzed, combining specific project, the design plan of algorithm, the calculation of key parameters and the function block chart of the control model were given. On the basis of spot debugging, the algorithm by drawing monitor AGC was improved, the mathematic formula of combinative control was given in theory, and the improved function module chart was shown.
