Abstract; In order to overcome the problem of low level of automation in traditional control, the metering device of quantitative material feeding
system is developed based on PLC and PID control algorithm. The system structure and configuration of PLC are described. In accordance with the
technical requirement of technique process, the practical conditions in industrial material feeding are considered systematicaly for both hardware
and application program in control system. The results of operation proved that the system is stable, reliable, with flexible and directly perceived
man-machine interface. Various functions implemented the system meet technique requirements. Excellent efects of application are obtained.
