薄鋼片在日常生活中之應用日漸廣泛，而其製造過程皆免不了要經過張力控制下的高速盤捲，在此高速盤捲中除須維持穩定的張力外，由於鋼片左右厚度存在些微之差異或盤捲中各滾輪存在有些微之偏斜，這些因素皆會導致鋼片盤捲時會偏離中央位置而擠向盤捲輪之一側，本研究即針對此高速盤捲的偏離問題，分析探討其動態特性，並設計提出其有效之糾偏控制方法，以確保高速盤捲的順暢穩定。
本研究係以實驗室之鋼片高速盤捲實驗機台為主體對象，分為前段糾偏與後段糾偏，前段糾偏係以一平移致動平台藉一軸心及連桿而帶動前滾輪產生一小幅左右擺動，再以此擺動角度調變前段系統的偏離方向與速度，後段糾偏係以二平移致動平台分別推動後頂輪之左右支撐座而產生一小幅上下偏轉，再以此偏轉角度調變後段的偏離方向與速度，前後段糾偏皆以光學邊緣位置感測器來偵測回饋鋼片的偏離位置。針對此設計之糾偏系統架構，本研究分析推導其動態模型，從而模擬其動態行為與分析設計其控制補償策略，並進行實機測試驗證，從實驗結果證實所設計提出之控制補償策略有效。

Ultra-thin steel sheet is widely applied in our daily life, the high speed winding systems must be have tension control during production, in addition to maintain stable tension in high speed winding, because of the both sides of steel sheet thickness maybe different or some rollers are not level enough ,those factors can lead to deviate center location, this research that is deviate problem of winding with high speed analyze and discuss dynamic characteristic, this research that is deviate problem of winding with high speed analyze and discuss dynamic characteristic, and design control method with effect to ensure the high speed winding system is stable.
The ultra-thin high speed winding system is the object of this study, which is divided into Front-end Alignment System and Rear-end Alignment System, the Front-end Alignment System is actuated by pushing the mobile platform which has a rotate axis, such action will cause an angle to modulate the direction and speed of Front-end Alignment System, the Rear-end Alignment System is actuated by two mobile platform pushed the left and right support units of rear Lifting Wheel respectively, such action will cause an angle to modulate the direction and speed of Rear-end Alignment System, all of sensors for Alignment control used edge sensing to feedback deviation of steel sheet, in the light of Alignment system framework, we analyze and derive the dynamic model, and then Simulate dynamic behavior and analyze control strategy to test and verify, and then Simulate dynamic behavior and analyze control strategy to test and verify, the control compensatory strategy is effective from experimental results.
