Abstract

A Suspension system can be defined as the mechanism that physically separates the car body from the car wheels. The purpose of any suspension system is to increase the ride comfort, road handling and stability of closed loop system. The suspension design must be compensate the effect of conflicting criteria of road holding, load carrying and passenger comfort. An active suspension system has been proposed. A quarter-car two degree-of-freedom (2DOF) system is designed and constructed to simulate the actions of an active quarter car suspension system. White noise input is introduced to a given system to expressed unpaved road and both step input and sine wave input are studied as well. The control strategy is based on two degree of freedom PID controller. (MATLAB/ Simulink) is used to verify the proposed algorithm. The comparison between the passive and active suspension and the results obtained from a range of road input simulations in the proposed algorithm shows the effectiveness of the proposed algorithm and best results are obtained.
