Aiming at the requirements of straighten processing tubes and shafts,an integral separation PID control arithmetic based on PLC was presented.The PID controller was implemented by PLC,actuator was high frequency response servo control system. Application indicates that the system has high response speed,small overshoot,high straightening accuracy and repeated positioning accuracy.
