Application to a Winding Machine

Abstract

Web transport systems allow the operations of unwinding and rewinding of various products including plastic films, sheets of paper, sheets, and fabrics. These operations are necessary for the development and the treatment of these products. Web transport systems generally consist of the same machine elements in spite of the diversity of the transported products. A reduced pilot-plant of an industrial web transport system allows studying of the different operations. The characteristics of this pilot-plant and its control device are presented in the following. The control of these systems is not simple because their dynamic characteristics change throughout unwinding. Moreover, quality standards of rewinding and the requirements of manufacture are often very constraining. The FTC system associated with the fault diagnosis module should improve the control performance without leading to undesirable consequences such as faults or catastrophic breakdowns [124].
