Evaluation of the Ride Comfort of an Active Suspension System for 1/4 Car Using PID and Fuzzy Controllers in MATLAB/SIMULINK

Abstract

The study evaluates the ride comfort of a 1/4 car active suspension system under various road conditions with continuous excitation frequencies, using PID and Fuzzy controllers. A simulation model was developed in MATLAB/SIMULINK to compare the performance of the two controllers. Results indicate that the PID controller demonstrates high accuracy and effectiveness in reducing vibrations, while the Fuzzy controller, despite being more flexible and efficient, faces challenges in achieving precise and smooth control. The study highlights the superiority of the PID controller in applications requiring high stability and rapid response.
