Fuzzy Logic Level Control of a Coupled Tank System with Raspberry Pi Application

Abstract

An implementation of a Fuzzy Logic-based control system for regulating the liquid levels in a coupled tank system is aimed in this study with the integration of a Raspberry Pi platform for real-time control and monitoring. The coupled tank system serves as a representative model for various industrial and engineering applications where precise liquid level control is essential. The system includes an ultrasonic sensor to provide real-time feedback on tank level, enabling the Fuzzy Logic controller to make informed decisions. The Fuzzy Logic controller is designed to respond to varying operating conditions and disturbances, offering a level of adaptability that conventional control systems often struggle to achieve. The fuzzy membership functions and rule base are carefully crafted to suit the specific characteristics of the coupled tank system. The results of this research demonstrate the effectiveness of the Fuzzy Logic controller in maintaining stable liquid level in the coupled tank system while minimizing oscillations and overshoot. The Raspberry Pi platform allows for remote monitoring and control through a user-friendly interface, providing a practical and cost-effective solution for industrial applications.
