摘要

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 derived from the stiffness matrix concept, which shows the relationship between the DC gain of the controller and that of the system. Root locus analysis was performed to validate the stability condition derived. The results of the software simulations and the experiments demonstrate the effectiveness of the proposed controller under various tension conditions.
