A nonlinear and coupling model is established according to the multi-layer register system working principle in gravure printed electronic equipments, and then, the linear model of the register system is constructed based on one order Taylor formula. In order to improve the speed and accuracy of register control, a feedforward PID control algorithm is presented according to the linear model in multi-layer register system. This algorithm is unique in that it uses the PID to adjust the inputs of the register system, and feedforward compensation for the known disturbance, making the register control accuracy has been greatly improved. The simulation shows that the proposed register controller is able to realize a high precision control for the register system and endowed with better control performance than PID controller in register control.
