摘要
针对当前切纸机控制中,送纸辊和切纸辊之间速度协调控制的问题,提出一种基于模糊PID的控制方案。为实现该方案,以PLC作为主控芯片,通过变频器实现送纸辊和切纸辊速度的采集和控制,然后在切纸辊控制中,引入模糊PID控制方法,以实现主从轴的位置控制。最后,设定试验参数,通过试验验证构建的控制方案,使得切纸辊和送纸辊之间速度大致一致,并且切纸的误差小于1mm,具有很大的优势。
In view of the speed coordination control between the paper feed roller and the paper cut roller in the current paper cutting machine control, a control scheme based on fuzzy PID was proposed. In order to realize the scheme, PLC was used as the main control chip to realize the speed collection and control of the paper feeding roller and the paper cutting roller through the frequency converter. Then, in the paper cutting roller control, the fuzzy PID control method was introduced to realize the position control of the master-slave axis. Finally, the test parameters were set, through the test to verify the control scheme constructed in this paper, made the speed between the paper cutting roller and the paper feeding roller roughly consistent, and the error of the paper cutting was less than 1 mm, which had a great advantage.
