Design and Simulation Study of Fuzzy Parameter Self-tuning PID Controller

Zhang Rui-bin

Abstract

In order to realize the PID parameter self-tuning,a fuzzy self-tuning PID controller which follows the PID parameters optimizing laws,and uses fuzzy logics to do automatic on-line tuning of PID parameters is designed for the temperature control system of crystal growth furnace based on PID control and fuzzy control.In comparison with conventional PID temperature control system,this temperature control system features high control precision and good adaptability.The simulation shows its validity and practicability.
