Active Vibration and Flatness Control of a Strip in a Continuous Galvanizing Line using Positive Position Feedback Control

Abstract: In this paper, we propose active vibration control of a strip in a continuous galvanizing line (CGL) using positive position feedback (PPF) control. The control system includes five pairs of electromagnetic actuators and controllers. First, the overall system was modeled using the three-dimensional finite element modeling (FEM) package ANSYS. The Krylov subspace technique was then used to reduce the order of the model. Finally, PPF control was applied to control the vibration. The stability condition was deriv… Show more

“…For this reason numerous examples show the successful use of a variety of methods that can be assigned to active damping by harmonic disturbance rejection. These include the application within mechatronic single-input single-ouput (SISO) systems, e.g., SMDSs [16]- [19], disk drives [20]- [22], gearboxes [23]- [25], and furthermore the control of power electronic devices [26], [27] or industrial processes [28]- [31].…”

“…Magnetic guideways that are capable of guiding a target in a noncontact manner, i.e., by utilizing electromagnetic force, have been actively considered for the manufacturing process of a thin steel plate that particularly considers the deterioration of surface quality caused by contact with a roller. In some of the existing techniques, electromagnets are installed on the upper and lower surfaces of a steel plate to support continuous steel plates in a noncontact manner by utilizing an attractive force [1][2][3][4][5]; however, to the best of our knowledge, suppression of out-of-plane vibrations have not been reported. Furthermore, these studies on this subject considered only linearly transported continuous steel plates.…”

“…Here, the strip would be more accurately modeled as a plate rather than a beam, cf., e .g. [7], where the strip is modeled as a plate considering purely elastic deformation only. However, based on the state of elasto-plastic deformation calculated with the beam model and the material model (5) for plane stress, the tendency of the strip shape in lateral direction can be captured, cf.…”
