卷接机组工艺风力与除尘系统自适应PID控制的实现

Self-Adaptive PID Control Syetem for Cigarette Factory Air Supplting and Dusting of Cigarette Making and Tipping Machines

对卷烟厂卷接机组工艺风力与除尘系统进行了描述,指出了其常规PID控制系统存在的缺点,分析了自适应PID控制原理和偏差等级划分的原因,给出了PLC自适应控制程序流程。在此基础上,设计了基于偏差等级的自适应PID控制系统,满足了系统受到扰动时,除尘主管内风压、风量能快速恢复到烟机正常生产所要求的状态。

In this paper,cigarette factory air supplying and dusting system is described.Shortcomings of Air Supplying and dusting system for conventional PID are pointed out,Self-Adaptive PID control principle and the reasons for deviation classification are analized,and the flow chart of PLC Adaptive control program is written out.On this basis,Self-Adaptive PID control system based on deviation classification is designed.With fluctuation of wind pressure and air volume caused by disturbance,the system can quickly recover to the set state required by Cigarette making Machine.
