摘　　要：详细地介绍了DAGC算法的推导过程,对DAGC调节系数引入原理和算法稳定性作了分析,阐述了DAGC与具体应用策略的关系,分析得出用DAGC可以提高厚控精度,并在单机架热轧铝合金中厚板轧机上证实了其分析。实际应用证明,采用DAGC代替原有GMAGC厚控数学模型取得了预期效果,在缺少测厚仪的条件下,不同规格铝板的同板差和异板差控制精度均可控制在合同指标内。The derivation process of the DAGC algorithm was introduced in detail,the principle of introducing the DAGC adjustment coefficient and the stability of the algorithm were analyzed,and the relationship between DAGC and specific application strategies was explained. The analysis concluded that the use of DAGC could improve the thickness control accuracy,and were confirmed on a single stand hot rolling aluminum alloy plate mill. The actual application proved that using DAGC to replace the original GMAGC thickness control mathematical model could achievce expected results. In the absence of a thickness gauge,the control accuracy for same plate difference and different plate difference of different specifications of aluminum plates could be controlled within the contract indicators.
