Fuzzy control system simulation of retractable tail frame of scraper conveyor

Abstract

To achieve automatic retractable tail frame of scraper conveyor, we applied fuzzy control theory to the hydraulic system of the retractable tail frame, established transfer function model of electromagnetic valve-controlling-hydraulic cylinder, designed fuzzy controller, and carried out simulation of the system using SIMULINK in this paper. Through simulation, we compared the dynamic performance of fuzzy controller with that of conventional PID controller, and ultimately verified the feasibility of fuzzy control technology in retractable tail frame of scraper conveyor.
