Optimum control system of tension process for filament winding systems

近年来，碳纤维（CF）和碳纤维增强塑料（CFRP）作为一种具有优异柔韧性和耐久性的材料受到了广泛的关注。此外，由于CF和CFRP虽然重量轻，但强度是材料的十倍左右，因此对其的要求越来越高。CFRP一般采用纤维缠绕法，即FW缠绕法。为了用这种方法制作出声音良好的产品，在绕线过程中绕线间距和绕线张力的控制是非常重要的。然而，具有测量和控制卷绕张力能力的先进卷绕机却很少。环形缠绕法和螺旋缠绕法是CFRP成型的代表性缠绕法。CFRP通过使用这些缠绕模式变得高强度。因此，有必要控制两绕组处的张力。通过笔者以往的研究，对张力控制系统进行了研究，圆环缠绕控制满足控制要求。但是螺旋缠绕还没有。为了满足螺旋卷绕过程的控制要求，本文对螺旋卷绕过程进行了分析，并采用系统辨识方法建立了张力过程模型。

Recently, Carbon Fiber(CF) and Carbon Fiber Reinforced Plastics(CFRP) have lately attracted as material which have the properties of excellent flexibility and durability. Moreover, since CF and CFRP have strength about ten times than material in spite of light weight, its demand gets more and more high. CFRP is generally formed by a Filament winding, namely FW method. In order to make a sound products by this method, the winding pitch and the winding tension control in the winding process are of great importance. However there are few advanced FW machines with capacities to measure and control the winding tension. Hoop winding method and Helical winding method are representative ones to form CFRP. CFRP becomes high strength by using these winding patterns. So it is necessary to control tension at the two winding pattern. By author's past research, tension control systems have been studied, and Hoop winding control has satisfied control specification. But Helical winding has not been yet. The purpose of the present research is to satisfy control specification for Helical winding process, where Helical winding process is analyzed and tension process model is constructed using a system identification method.
