摘 要: 超薄快速鑄軋同常規(guī)鑄軋相比，板形奇異機理復雜，板形現象突出。根據鑄軋板形缺陷的表征特點，建立了鑄軋板形的數學描述。將板形檢測信號視為動態(tài)時間序列，運用自適應濾波理論，建立了一種通用的板形檢測信號除噪方法。仿真結果表明該法除噪效果明顯，能滿足實時控制要求。

Abstract: The fast ultrathin gauge roll-casting for aluminum strip rolling is a kind of highly efficient technology with obvious flatness phenomenon. The research focus in the roll-casting field is to ascertain the cause of flatness defect and to seek the way of automatic flatness control. According to the characterization of roll-casting strip shape, the mathematical expression of the roll-casting flatness was established. Flatness detection signal was looked on as dynamic time series and by the theory of adaptive filtering a general method was developed to remove the harmful noise from the flatness detection signal. Simulation result proves that the method can be used in real time control with good effect.
Key words: roll-casting; flatness detection; adaptive filtering; flatness control
