MODELING AND TENSION CONTROL OF AN INDUSTRIAL WINDER WITH DANCER MECHANISM

摘要

The plant considered in this paper is an industrial winding system with pendulum dancer mechanism. Such dancer have been rarely presented and modelized in publications. Transport system dynamics change dramatically due to the wide variation in roll radii and inertia. Industrial systems typically use decentralized PID controllers. In this paper we present the model and the industrial control performances of such winding system. A multi-model H_(infinity) robust control with gain scheduling significantly reduces coupling between web tension and velocity. Performances of this new controller and industrial controller are compared. The adjunction of an internal stresses model allows us the on-line simulation of the stresses in the winding roll.
