目的为了提高凹版印刷电子装备的制造精度和一致性,提出一种将模糊控制与PID(Proportion-Integral-Differential)控制有机融合的多层套准系统控制策略。方法在2层套准系统模型基础上,结合多层套准系统的套印工艺,建立4层套准系统非线性耦合数学模型,有机结合模糊控制和PID控制设计4层套准系统模糊PID控制策略,并利用Simulink软件对所提出的控制策略进行仿真研究。结果仿真结果表明,提出的套准系统模糊PID控制策略很好地抑制了张力波动、速度干扰、料带性能变化引起的套准误差。结论提出的多层套准系统控制策略实现了高精度套准控制,具有比PID控制器更好的控制性能。

Register System Control Strategy Based on Fuzzy Control for Printed Electronic Equipment

The paper aims to propose a multi-layer register control system that integrates fuzzy control and PID (Pro-portion-Integral-Differential) control to improve the printing accuracy and consistency of gravure printed electronic equipment. A four-layer nonlinear and coupling model was established according to the multi-layer register system working principle and the two-layer register system model to effectively integrate fuzzy control and PID control to design a fuzzy PID control controller for the four-layer register system, and then, the simulation study of the controller was executed in the Simulink. The results of computer simulation showed that the proposed control methodology well restrained the register errors caused by tension fluctuation, speed interference and web characteristic change. The proposed multi-layer register controller is able to realize a high precision control for the multi-layer register system. It has better control performance than PID controller.
