摘　　要：介绍了各种厚度控制策略在河北中钢1 250 mm八辊五机架全连续冷连轧机组中的应用。针对S1监控AGC的大滞后问题,提出了采用改进后的Smith预估控制算法,并通过Matlab仿真和现场运行证明此算法有较好的鲁棒性。在实际轧制过程中,各种AGC的综合应用实现了带钢厚度的精确控制,现场运行取得了良好的效果。Applications of various automatic gauge control strategies in Hebei Zhonggang 1250 mm 8 high 5 stand continuous tandem cold mill are introduced. To counter long time delay problem of monitoring AGC applied in the first stand （S1）, an improved Smith predictive control algorithm was presented. By using Matlab language, simulation and practical operation show that this algorithm has better robustness. With application of AGC, accurate control of strip thickness was achieved and satisfactory control effect was obtained in practice.
