Application and research of fuzzy self-tuning PID in industrial temperature control system

Song Guo-yi

Abstract

This paper chooses the right control algorithm by characteristics of industrial temperature.It discusses principle and design of fuzzy PID controller and mathematical model of the controlled objects are given.Simulation model are created by Matlab/Simulink simulation tools.Simulation results of PID control,fuzzy control and fuzzy PID control are compared by unit step input.As a result,the better dynamic response is derived by fuzzy self-tuning PID control.
