Comparative Study of Pid and Fuzzy Controller on Embedded Computer for Water Level Control

چکیده
This study deals with one of frequently encountered tasks in process industry – accurate water level control. Proportional Integral Derivative (PID) control is often used for this purpose. Since control parameters of PID controller are fixed and tank system is inherently nonlinear, PID controller should not be used on wider level range. Therefore this study analyzes the effectiveness of water level control using fuzzy controller. The fuzzy controller is implemented based on mathematical model of tank by using MATLAB Simulink. The graphical user interface (GUI) is designed by using LabVIEW software and PID and fuzzy controllers are implemented on Microcontroller board. Microcontroller board is used as an acquisition board for collecting Ultrasonic Sensor data from level of water in tank system and as a voltage generates for water pump to pump the water into the tank. Experimental results confirm that the fuzzy control system has good adaptability in comparison with PID and provided satisfying results.
