Comparison of Performance Analysis of PD-FLC in Controlling and Monitoring Water Level in the Tank with SISO-FLC and MISO-FLC

Abstract

In this study, three different techniques for controlling water levels in a tank are compared: the single-input single-output (SISO) fuzzy logic controller (FLC), the multiple- input single-output (MISO) FLC, and the proportional-derivative (PD)-FLC. By conducting simulations using MATLAB/Simulink, it was discovered that the PD-FLC approach outperformed the other two techniques in various aspects. Specifically, the PD-FLC method demonstrated a superior response time, enabling it to quickly adapt to changes in water levels and maintain the desired level effectively. Moreover, the execution speed of the PD-FLC technique was excellent, as it efficiently processed input variables and provided precise control signals to ensure smooth water level control. One notable advantage of the PD-FLC approach was its ability to prevent overshooting, which can cause instability and inefficiency in control systems. By effectively maintaining stable water level control without overshooting the desired setpoint, the PD-FLC technique proved to be highly efficient in this study.
