Abstract

This paper studies the effect of optimal damping control suspensions on vehicle ride performance. The gain matrix is developed from second-order equations with the road roughness represented by a stochastic process. With only velocities as the feedback signal, the number of unknowns and measurements is reduced leading to more efficiency in data processing. The control is implemented on a quarter-car model which includes the tire damping effect. The spectral density is compared with those for passive and fully active systems.
