一般而言，於捲繞式製程中，基材的傳輸平穩度及位移精確度為影響軟性電子加工品質良劣的關鍵因素。因而在發展此類捲繞製程設備時，如何設計良好之張力控制及傳輸速度控制系統極為重要。在張力控制部份，本論文提出一種考慮系統動態慣性矩及摩擦力影響之無感測器張力估測法則並結合干擾量補償架構應用於捲繞張力控制系統架構中。另外在傳輸速度控制方面，本論文提出干擾補償架構應用於速度控制系統中。由於在捲繞系統中，摩擦力及外部干擾量會對系統的性能造成很大的影響，因此本論文在張力控制以及傳輸速度控制方面皆採用干擾量補償架構，以解決捲繞系統在運作時所遭遇到的干擾問題。特別是在干擾量補償架構方面，本論文引入H-infinity控制理論進行分析與探討，並利用MATLAB設計H-infinity補償器。最後透過捲繞系統實作以驗證本論文所提方法之可行性。

Generally speaking, in the winding-type process, transport smoothness and positioning accuracy of the flexible substrate are crucial to the quality of flexible electronics products. Therefore, developing core technologies such as tension control and the transmission speed control for the roll-to-roll system is essential for the development of the flexible electronics industry. We will focus on the study of the tension control and the speed control for the roll-to-roll system. For the tension control problem, a sensorless tension estimation algorithm in proposed which considers friction as well as the change of the moment of inertia using a disturbance compensation scheme. The algorithm is applied to a roll-to-roll system in order to improve process accuracy. For speed control, a disturbance compensation scheme is used in the speed control system architecture. Since, in the roll-to-roll system, friction and external disturbances will significantly affect performance of the winding control system, both the speed control and tension control scheme use a disturbance compensation scheme to solve the problem of encountered disturbances. In particular we introduce H-infinity control theory to analyze and discuss the disturbance compensation scheme. The H-infinity compensator is designed using MATLAB. Finally, experimental results verify the feasibility of the proposed approach.
