在压力AGC通用表达形式的基础上,考虑辊缝位置环,采用解析方式推导出BISRA-AGC变刚度控制的出口厚差表达式,并对控制算法的快速性、稳定性和终值误差进行定量分析。仿真结果与分析结论一致,所得结论可以作为工程上算法选择与参数设定的参考。 Based on the general expression form of pressure AGC, taking into account the position gap of roll gap, the expression of outlet thickness difference of BISRA-AGC variable stiffness control is deduced analytically, and the rapidity, stability and final error of control algorithm are quantified analysis. The simulation results are consistent with the conclusions of the analysis, and the conclusions can be used as a reference for engineering algorithm selection and parameter setting.
