The objective is to develop a smart adaptive suspension system that dynamically varies the damping coefficient to achieve better control and improve the ride quality of an automobile. Adaptive/semi-active systems can only change the viscous damping coefficient of the shock absorber, and do not add energy to the suspension system. Though limited in their intervention, semi-active suspensions are less expensive to design and consume far less power. In recent times, research in semi-active…
