The winding process of film materials is a highly nonlinear dynamic system to maintain tension at constant value. Some tension control architectures are proposed for winding process of the film materials under various feeding speeds at pinch rolls. The proposed control architectures include PI, PID and fuzzy tension control systems. The PI and PID methods are traditional control architecture, while the fuzzy tension controller is an intelligent control method. The translation-width idea and sliding-mode technology are embedded into fuzzy inference engine to remedy chattering phenomena and only one parameter needs adjustment. To confront the uncertainties existed in practical applications, an adaptive tuner is added to adjust the parameter for further assuring robust and optimal performance. The performances of the proposed three control methods are indicated in comparison with each other. The winding process of film materials with the fuzzy controlling architecture possesses the salient advantages of simple control framework, free from chattering, stable tracking performance and robust to uncertainties.
