On a new approach for gravure/offset printing pressure control algorithm development using the full state feedback controller

In the paper, a mathematical model of roll printing pressure control system using the pneumatic system is proposed. By writing the system of dynamic equations in strict feedback form and applying the back-stepping theory, a full state feedback controller is obtained with gains that are determined optimally by modified genetic algorithm (MGA). A printing pressure control algorithm is given by using the proposed mathematical development and controller. The simulation results employed in Matlab/Simulink show the stability and high precision of the proposed algorithm.
