Research on the Winding/Unwinding Control System Based on Fuzzy Control Theory

摘要

A fuzzy controller of the wioding/unwinding control system used in jig-dyeing machine is introduced,which is superior to the one with conventionaI optimal PID controller in convergence speed and stability.Its mathematical model and trausfer function are presented hased on mechanism of the winding/unwinding control system.Simulation of the fuzzy controller carried out in the MATLAB(Simulink)environment proves that the control system based on fuzzy controller is superior in quality,precision and operation to a conventional optimal PID controller.The outlined experimental results also show the effectiveness and the robustness of the fuzzy PID controller in good dynamic performance,high robustness to parameter variation and disturbance.
