Synthesis and Implementation of Different Control Law Strategies for a Winding Process

Abstract

This article presents the synthesis and the real tests of three control law strategies to a winding process. The principal no linearity of this type of system is due to the variation, during operation, of the radius of the winding reels. A linear time varying model can thus describe the dynamic behavior of this system. A linear optimal control law, a gain scheduled controller and a non linear control law (input-output linearizing and decoupling approach) are selected for the control law synthesis. These control laws are then applied to the process with a DSP dSpace board interfaced with Matlab/Simulink. The experimental results illustrate the decoupling advantage of the nonlinear approach.
