Optimization and Experimental Study of Multi Parameter Cooperative PID Algorithm for Packaging Stretch Wrapping Machine
摘要
Abstract
To address the problems of tension instability,low rotational speed matching,and poor uni-formity of wrapping layer in a packaging stretch wrapping machine during variable diameter wrapping and operations with variable film materials,and considering the multi parameter coupling characteristics of"tension-rotational speed lifting",a parameter self-tuning PID optimization algorithm based on compre-hensive deviation judgment is proposed,and a multi parameter collaborative control system with PLC as the core is constructed.By analyzing the laws of mechanical deformation and motion coupling of the wrap-ping film,a multi-dimensional dynamic model of incorporating tension,rotational speed and lifting is es-tablished.A PID dynamic tuning strategy based on coupling deviation grading is designed,and both algo-rithm simulation and multi-condition experimental verification are performed.The results show that with the optimized PID algorithm,the system tension overshoot is≤4.2%,the adjustment time is≤0.65 s,the steady-state error is≤±0.6%,and the uniformity error of the wrapping layer spacing is≤±1.8 mm.Compared with the traditional PID controller,the control accuracy and anti-interference capa-bility are improved by more than 65%.The system can accommodate a packaging diameter range of 0.3-0.8 m and the wrapping requirements of two mainstream film materials,PE and PVC.This work provides a new technical pathway for the automation and refined control of stretch packaging wrapping machines.关键词
