PID and fuzzy logic approach to vehicle suspension system control

Abstract

Active suspension systems can improve the drive comfort of passengers and road grip capacity of the vehicle and it is also important for the safety of drive. For such advantages of the active suspension systems, it plays major role to control of suspension system. In this study, a quarter car model was designed in MATLAB/Simulink and then this model was controlled respectively by using the methods PID controller and Fuzzy Logic controller for comparing this methods. Comparing both methods, PID control method outperforms fuzzy logic one.
