Modeling and Control for a Coating Machine

Abstract

Velocity and tension controls are important factors for the film in the coating machine. In this paper, an experimental coating machine is established to make control analyses. The mathematical model of the coating machine is firstly derived. Then, the sliding mode control (SMC) is used to control the tension and the velocity of the film. Finally, some experimental results are proposed to show the performance of the SMC scheme in the experimental coating machine.
