卷筒料印刷装备收卷张力系统解耦控制研究

目的 为了保证卷筒料印刷装备收卷张力系统的性能，提出一种适用于收卷张力系统的自抗扰（ADRC）解耦控制器。方法 在收卷张力系统数学模型基础上，结合卷筒料收卷系统的工作原理，基于ADRC控制技术设计收卷张力系统的ADRC解耦控制器，并利用Simulink软件对所提出的控制策略进行仿真研究。结果 在相同的阶跃输入下，研究结果表明，PID控制器调整时间为2.4 s，而ADRC解耦控制器调整时间为0.7 s；在PID控制下，收卷基材张力出现超调和震荡，而在ADRC解耦控制下，基材张力无超调和震荡现象；采用PID控制器，收卷牵引跨度张力变化引起收卷跨度张力波动，而采用ADRC控制器则没有波动。结论 提出的卷筒料印刷装备收卷张力系统ADRC解耦控制器实现了高精度张力控制，具有比传统PID控制器更好的控制性能。

Decoupling Control for Rewinding Tension System of the Roll to Roll Printing Equipment

The paper aims to propose a decoupling controller based on active disturbance rejection control (ADRC) for rewinding tension system to ensure the performance of the rewinding tension system in roll to roll printing equipment. Based on the mathematical model and the working principle of the rewinding tension system, the ADRC decoupling controller of the rewinding tension system was designed, and then the proposed controller was simulated in Simulink. Under the same step input, the results showed that the adjusting time of the PID controller was 2.4 seconds, while that of the ADRC decoupling controller was 0.7 seconds. The tension of the rewinding substrate had overshoot and oscillation in the PID controller, but there was no overshoot and oscillation in the ADRC decoupling controller. With the PID controller, the tension fluctuation of the rewinding span was caused by the tension change of the rewinding traction span, while there was no fluctuation in the ADRC decoupling controller. The proposed ADRC decoupling controller is able to realize high precision control of the rewinding tension system and is endowed with better control performance than PID controller.
