针对活套在热连轧中存在的角度和张力耦合控制作用,在保证穿带稳定性和轧制最优张力控制中,本文提出了ILQ逆线性二次型进行的活套优化控制设计。在张力连轧阶段,对活套模型利用反馈逆线性二次型ILQ理论进行优化设计,通过理论推导来提高参数的可调性,并将其应用到迁钢1580的活套优化设计中,仿真和实验验证了该方法的有效性。

The looper has the coupling effect of angle and tension in hot strip rolling.In order to ensure the stability of threading and the optimal tension control in rolling,this paper presents an optimal control design of looper using ILQ inverse linear quadratic form.In the stage of tension continuous rolling,the improved looper model is optimized by using the feedback inverse linear quadratic ILQ theory,and the adjustability of parameters is improved by theoretical derivation,and it is applied to the looper optimization design of Qiangang 1580.Simulation and experiment verify the effectiveness of the method.
