Research and Applications of Fuzzy-PID Control on PFPL

This dissertation mainly introduces Fuzzy-PID Control which are used in the PFPL (Pseudo-flexible Production Line). The servo system plays an important role in the NC machine. The performance of servo system decide the quality of NC machine in very great degree This dissertation research and develop a milling and paring manufacture unit of open CNC system – Numerical control unit of PFPL. By using the GT-SV motion controller, put up the software and hardware platform of NC unit rapidly with module design method and the target-oriented programming idea. Take NC milling machine as the process platform, this dissertation use intellectual PID control method to improve the servo control of motion controller, through the pointing accuracy survey of the milling machine, confirmed the actual effect of Fuzzy-PID control.
