The purpose of suspension system isto minimizethe vibration that is being
transmitted to the passenger compartment of vehicle and thereby reinforce rider comfort.
The traditional suspension system has fixed criteria for spring and damping. The
performance of the suspension systemcan be improved by dynamically varying the stiffness
and damping coefficient of the suspension system elements which can be achieved by
introducing active suspension system. In this study, the performance of passive and active
suspension system for a quarter-car model are analysed using MATLAB SIMULINK
package.A Proportional Integral Derivative (PID) control, Fuzzy tunedPID control and
Particle Swarm Optimization (PSO)tunedfuzzy control techniques are used to control the
dynamic characteristics of the active suspension system. The characteristics of PSO rules
areframed to reduce the sprung mass acceleration. The results showthat PSO tuned fuzzy
controlapproach issignificantly improvingthe overall performance of the active suspension
