基于PID控制的烟草烘丝机温度控制系统研究

Study on Temperature Control System of Baking Cut Tobacco Machine Based on PID Control

在烟草加工过程中,烘丝环节直接影响烟草质量的好坏,而对温度的控制是烘丝环节的关键所在。该系统提出通过传感器采集烘丝机滚筒内部的温度信号,送入PID控制器运算比较,再通过PLC控制变频器对滚筒调速,能解决加热过程的迟滞效应,并可对温度进行稳定控制。

During processing tobacco, baking cut tobacco step directly influenced tobacco quality, and temperature control was the key of the step. The system put forward that through sensor to collect temperature signal in internal roller, deliver it into PID controller to calculate and compare, then, regulate roller speed by using PLC control transducer which can resolve retardation effect and control the temperature stability.
