In order to improve the ride comfort and stabilityby reducing the body acceleration in vehicles caused by the roadirregularities, suspension system plays an imperative role inretaining the continuous road wheel contact for better roadholding. In this paper, a quarter-car suspension model has beenconsidered and a PID controller has been designed for the same.The aim of the work described in this paper is to illustrate theimprovement of response of the system by optimizing the PIDcontrollers using genetic algorithms. In the conclusion, by acomparative analysis between the conventional PID tuningmethods and optimization carried out using genetic algorithmsoffers lesser oscillatory and better response.
