Design and Simulation of Closed-Loop Control System for Screw Oil Press

Abstract

The traditional screw press has many disadvantages, such as the lower level of automation, the existing unstable control system and the longer response time. Through the research on the principle of pressed oil, mechanical structure and the automatic control procedure of the screw press, a set of automatic closed-loop control system of the screw press has been designed, which is based on Programmable Logic Controller (PLC) control and Proportion-Integration-Differentiation (PID) control strategy. For this control system a simulation model is established using Simulink, and the simulation experiment and analysis are also presented. It is shown that this system could greatly improve the level of automation of the screw press and provides certain reference to the design of intelligent control system used for large oil press.
