A Mold Level Mechanism Model in Continuous Casting with Application to Suppression of Limit Cycle
-
摘要: 针对结晶器液位极限环抑制中dither抖动参数难于确定的问题,建立了整个连铸机结 晶器液位的机理模型,正确预测了液位控制中的极限环现象.以此模型为基础,提出了一种 dither抖动参数工程整定方法.Abstract: This paper proposes a mold level mechanism model in continuous casting. It captures the limit cycle oscillation in mold level control. Based on this model, a parameter-tuning method of dither signal is proposed, which can be used to suppress the limit cycle oscillation.
