Study and Application of Fuzzy PID Intelligent Control

Abstract

In the boiler automatic control system, there are some characteristics of time-varying, large lag and many disturbances in the process of boiler superheated steam temperature control. The traditional PID control cannot achieve the desired control effect, so an intelligent control algorithm called fuzzy PID control is proposed. Fuzzy PID control is based on the PID algorithm, with the error and error rate as input, using fuzzy rules for fuzzy control. By comparing the PID control algorithm with the fuzzy PID control algorithm in MATLAB simulation, the superiority and feasibility of the fuzzy PID control algorithm are verified.
