摘要
目的为了解决张力控制不稳定对瓦楞纸板质量和生产效率产生影响的问题。方法对放卷辊进行动力学分析,建立瓦楞纸板的原纸张力数学模型,并分析张力稳定的主要因素。针对传统PID控制不能实现原纸张力控制过程中参数的自适应调整,提出一种变论域自适应模糊PID控制策略,采用变论域模糊控制实现控制参数自整定和控制规则的自调整,并将其应用于原纸张力控制系统中。结果仿真结果表明,该张力控制策略的响应时间约为0.65 s,最大超调量为3%。结论所设计的控制方法与传统的PID控制相比,具有响应速度快、抗干扰能力强、控制输出稳定等优点,能够实现原纸张力的稳定控制。
The work aims to solve the problem regarding the influence of tension control instability on the quality and production efficiency of corrugated board. Based on volume and dynamic analysis on the winding up roller, the mathe- matical model for the base paper tension of corrugated board was established and the main factors leading to the stable tension were analyzed. With respect to traditional PID control unable to achieve the adaptive adjustment of parameters in the process of base paper tension control, a variable domain adaptive fuzzy PID control strategy was proposed. The vari- able domain fuzzy control was adopted to realize the self-tuning of control parameters and the self adjustment of control, and it was applied in base paper tension control system. The simulation results showed that the response time of the ten- sion control strategy was about 0.65 s, and the maximum overshoot was 3%. Compared with the traditional PID control, the designed control method featured by such advantages as fast response speed, strong anti-interference ability and stable control output can achieve the stable control over the base paper tension.
