Applying Fuzzy Logic in Process Control System

Abstract

This paper describes a method of the level control in process control system. The control of the height (level) of the liquid in a tank bases on the value of the level error and the value of the differential of the level error. The fuzzy controller is used to control so that the height of the liquid is always constant regardless of noise. The results of the experiment and the simulation show that the controller meets our requirements. This results were applied specifically in the process control system (level, flow, pressure, temperature) of the mechatronic lab of the Ho Chi Minh City University of Technical Education
