摘　　要：目的为提高药品包装的贴标精度,设计一种基于双模糊PID控制器的贴标机张力控制系统。方法简要论述药品包装生产线结构及其工艺流程。针对标签纸带收卷过程具有时变性、非线性和动态干扰等特点,设计一种双模糊PID张力控制器。利用副模糊控制器实现主模糊控制器的变量论域系数整定,而主模糊控制器可实现PID控制器参数整定。通过实验验证所述控制系统的有效性。结果实验结果表明,与PID控制器相比,双模糊PID控制可使系统超调量减小50%,系统调节时间减小65%;贴标位置准确、标签贴附平整。结论所述控制系统具有较好的抗干扰性能,贴标效果良好,具有一定使用价值。The work aims to design a tension control system of labeling machine based on double fuzzy PID control-ler,so as to improve the labeling accuracy of drug packaging.The structure and process flow of drug packaging produc-tion line were briefly discussed.Aiming at the characteristics of time-variation,nonlinearity and dynamic disturbance in the winding process of label paper tape,a double fuzzy PID tension controller was designed.The parameter tuning of the main fuzzy controller was realized by the sub-fuzzy controller,while the main fuzzy controller could adjust the parame-ters of the PID controller.The effectiveness of the control system was verified by experiments.From the experimental results,compared with the PID controller,the double fuzzy PID control could reduce the system overshoot by 50%and the system adjustment time by 65%.The labeling position was accurate and the label was attached smoothly.The control system has good anti-interference performance,excellent labeling effect and certain use value.
