This paper presents a nonlinear register control scheme for the latest type of rotogravure printing presses referred to as the sectional drive system. In the printing presses, where each gravure cylinder is driven by an individual motor, tension fluctuations caused by an upstream register control generate register errors in downstream units. Therefore, development of the control system to reduce the register error propagation to the downstream is a challenging issue in the printing press. First, we propose a nonlinear coordinate transformation for the state variables in order to deal with the printing press dynamics easily. Then, based on the new coordinates, a nonlinear control law is designed with the Lyapunov stability theorem such that the register errors converge to zero. Finally, the performance of the proposed method is demonstrated by simulation and experiment carried out on a practical printing press, and a comparison with a conventional control method is also presented to show the effectiveness of the proposed control scheme.
