| 摘 要： | 卷取温度控制已成为带钢热连轧计算机控制系统的一项常规控制功能,但是热轧带钢卷取温度的控制还存在目标卷取温度控制精度差及带钢在宽度方向上的温度分布不均匀导致带钢变形等问题,针对以上问题建立了在带钢宽度和长度方向上的二维层流冷却温度控制模型,提出了二维最小均方误差(2DLMS)控制策略.最后,应用安阳钢铁集团第二炼轧厂1780热轧生产数据对该模型进行了仿真分析,结果表明该模型较现用的模型有更好的精确度,解决了低目标卷取温度控制精度差的问题,而且在宽度方向上温度分布区域均匀化,缓解了带钢变形的力度.对于研究热轧层流冷却温度控制系统用一定的参考价值和实用意义.

| Abstract: | The target of the laminar cooling control for hot strip mill is the coiling temperature.However,the control accuracy of the coiling temperature is not good enough yet.Besides,the temperature distribute in the width direction is ignored in the current control system which make the strip deform.Therefore,to solve these problems,a 2D model of the laminar cooling system is proposed first.Then,a 2DLMS control strategy is build to improve the performance of the laminar cooling system.At last,simulation was made u... |
