根据轧制原理,提出了支持向量机建立轧制力预报模型,并通过布谷鸟算法优化支持向量机参数,达到提高预报精度的目的。提出了支持向量机网络与数学模型结合的方法,对某“1+4”铝热连轧厂现场采集的5052铝合金轧制数据进行离线仿真,进一步提高了轧制力预报精度。在轧制规程设定中,建立了以预防打滑为主的电机功率剩余程度相近目标函数,并用布谷鸟算法对压下率进行优化,结果表明,该规程有很好的预防打滑效果,并能保证各机架电机的功率剩余程度相近。
根據軋製原理,提齣瞭支持嚮量機建立軋製力預報模型,併通過佈穀鳥算法優化支持嚮量機參數,達到提高預報精度的目的。提齣瞭支持嚮量機網絡與數學模型結閤的方法,對某“1+4”鋁熱連軋廠現場採集的5052鋁閤金軋製數據進行離線倣真,進一步提高瞭軋製力預報精度。在軋製規程設定中,建立瞭以預防打滑為主的電機功率剩餘程度相近目標函數,併用佈穀鳥算法對壓下率進行優化,結果錶明,該規程有很好的預防打滑效果,併能保證各機架電機的功率剩餘程度相近。

According to the principle of rolling, a forecasting model for rolling force based on support vector machine ( SVM) was proposed. In order to improve the prediction precision, the cuckoo search algorithm was used to optimize the parameters of SVM. The combination of SVM network with mathematic model was proposed. The offline simulation of 5052 aluminum alloy rolling data obtained on site of a “1+4” aluminum strip rolling factory was carried out to further improve the precision of rolling force prediction. The objective function based on the prevention of slip and residual power of motors was established in the specification of rolling and the rolling reduction was optimized by cuckoo algorithm. The results show that this method has good effects of preventing slip and can ensure similar residual power of each motor.
