  2. 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

    結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；塞棒頭和浸入式水口被腐蝕后引起控制精度差；浸入式水口堵塞物的突然脫落所引起的液位劇烈波動；無法克服拉速波動引起的擾動。
