A Fuzzy Adaptive PID Controller for Multilayer Register System of the Gravure Printing Machine

This paper presents a fuzzy adaptive PID control strategy Based on the fuzzy control and PID control to improve the printing accuracy and stability of the multi-layer register system for gravure printed electronic equipments. First, a nonlinear and coupling model is established according to the multi-layer register system working principle and the two-layer register system model. Secondly, the fuzzy PID adaptive control strategy is designed for the four-layer register system, and then, the simulation study of the proposed strategy is executed in the Simulink. Finally, the simulation results show that the proposed register strategy is able to realize a high precision control for the multi-layer register system and endowed with better control performance than PID controller in register control.
