Web register control algorithm for roll-to-roll system based printed electronics

In the paper, a review for web register control technology is presented. Based on the development of nonlinear control theory, a web register control algorithm is proposed for roll-to-roll system based printed electronics by using the non-linear feedback controller. The optimal gain of obtained controller is determined by using the modified genetic algorithm. The simulation results employed in Matlab/Simulink show the stability and high precision of the proposed algorithm.
