The control system of mould level is crucial to improve the slab quality in the continuous casting process , pid controller is used in the traditional mould level control , and it has some defaults , such as : at the start - up or finishing period of casting or during the changeover of tundish , pid control has a bad effect , its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate , and pid control can not overcome the disturbances resulted from the change of casting speed 结晶器液位控制系统是提高连铸产品质量的关键环节,传统的连铸机液位控制方法采用常规的pid控制,存在如下不足:开始、结束浇注和换中间罐浇注时,控制效果差,超调量大,过渡时间长;塞棒头和浸入式水口被腐蚀后引起控制精度差;浸入式水口堵塞物的突然脱落所引起的液位剧烈波动;无法克服拉速波动引起的扰动。
