Design of Industrial Control Configuration Software Based on Incremental PID Algorithm in Flow Control System

According to the flow control problem in the FESTO process control system's flow station,this paper introduced a new method for realizing incremental PID control,which made use of the industrial control configuration software function and ActiveX characteristic extension configuration software function.And the relationship among the control algorithm,field signals and configuration software was showed particularly.It shows a new experimental method for using configuration software to realize complex control algorithm in the field of industrial control.This system is figure visual,timely and programming simple and can meet the general demands in industrial control process.
