摘　　要：针对热连轧窄带钢稳态轧制过程中自适应增益系数α的确定进行探讨，以４５０ｍｍ热连轧机为仿真对象，分析各种影响增益系数α的因素，用数理统计中未知方差σ２的参数区间估计方法确定实测数据的置信概率，用参数寻优法建立了增益系数α和实测数据置信概率之间的定量关系，为在线确定增益系数α的值提供了依据。This paper explores the determination of gain coefficient α with adaptive control in continuous hot narrow strip rolling under steady condition,simulated on the 450 mm continuous hot strip mill,analysed every effect to gain coefficient α ,showed that the confidence levels of the measured data can be determined by parameter estimation with unknown variance σ 2 in mathematical statistics and the value of gain coefficient α can be got by parameter optimization,discussed how to set up the quantitative relation ship between the measured data and gain coefficient α and provided a basis for on line determination of gain coefficient α .
