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采用常規的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。 |
