| 目的 解决新型悬浮包装缓冲衬垫生产中薄膜张力难以控制的问题。方法 建立非连续覆膜环节中张力系统的数学模型，提出以LabVIEW为仿真软件，模糊自适应PID为控制算法的仿真策略。分析在不同卷径、不同加速度和加减速方式下，薄膜张力的变化情况和算法的控制效果。结果 仿真结果表明，薄膜卷径越小张力波动越大，运行加速度越大薄膜张力波动越大。在不同工况下，模糊自适应PID较常规PID有更快的响应速度和更小的超调量。结论 模糊自适应PID参数调整简单，适应性好，能满足非连续覆膜过程中薄膜张力稳定的控制要求。 |

| The work aims to solve the problem that the film tension is difficult to control in the process of producing the buffering cushion of new suspension package. The mathematical model for the tension system during the non-continuous film coating was established. A simulation strategy with LabVIEW as simulation software and fuzzy adaptive PID as control algorithm was proposed. The change of film tension and the control effect of the algorithm under different rolling diameters, accelerations and acceleration/deceleration modes were analyzed. The simulation results showed that, the smaller the film rolling diameter, the greater the tension fluctuation; the greater the running acceleration, the greater the film tension fluctuation. In different working conditions, compared with the conventional PID, the fuzzy adaptive PID had faster response speed and smaller overshoot. The fuzzy adaptive PID parameter adjustment is simple and adaptive, which can meet the control requirements of film tension stability in the non-continuous film coating process. |
