Implementation and Control of A Liquid Level Model

Abstract

Control engineering is an interdisciplinary field requiring knowledge on math and
physics, circuits, sensors, actuator, and microcontrollers. It also provides users experiences in
testing, simulation and real-time implementation. This paper aims to build and control a liquid
level stability model, which can be used to test different control algorithms. The proposed
solution is to build low-cost hardware based on Arduino Mega and the PID controller has been
built on MATALB/Simulink software for stable control of liquid level. Experimental results on
the PID controller shows that the response of the model has suitable setting time, negligible
overshoot and small steady-state error. With the above results, the model completely meets the
requirements of practice and experiment on system control.
