Design of flat screen printing asynchronic controller based on cross coupled control

针对平网印花机同步控制精度不高的问题,分析平网印花机同步控制系统和运动轨迹误差产生的机理,提出将CCC(Cross-Couple Control)交叉耦合控制应用于平网印花机同步控制器的设计,并设计出一种嵌入式CCC同步控制器。为了提高在线辨识被控对象的精确度,保证控制系统的品质指标,将模糊自整定PID算法应用到CCC同步控制器的设计中,最后在FPGA内部实现。仿真结果表明该方法能够有效的减小轮廓误差,可推广应用到其他行业。

According to the low synchronous control precision of Flat screen printing,the Flat screen printing＇s control systerm and the mechanism of trajectory errors are analyzed.Put forward the design of applying CCC（Cross-Couple Control） to flat screen printing synchronous controller,a embedded CCC synchronous controller is designed.In order to improve the controlled object online identification accuracy and ensure the quality control system,fuzzy self-tuning PID algorithm is applied to CCC synchronous controller which is realized in FPGA.Simulation results show that this method can effectively reduce contour error and can be applied to other industries.
