基于非线性辨识理论印刷墨区控制探讨

Study of Inking Zone Control Based on Non-linear Identification

基于非线性辨识理论,建立闭环的数学模型,寻求印刷流程中数字版面网点面积率与墨键开度之间的关系。通过实验证明:基于非线性辨识理论模型的建立,可以有效的弥补印刷生产中的扰动因素所带来的误差;由评价参数可知,该模型精度高、稳定性好,若将该理论应用于实践,可缩短印刷开机时间,提高印刷实效性。

A closed-loop mathematical model of inking zone control was established based on non--lin- ear identification theory. The relations between dot area of digital printing and inking key opening were resolved with the models. It was proved that the error produced in printing process can be effectively offset with the models; the model has high accuracy and good stability; the application of the models can shorten starting time and improve printing efficiency.
