Model following active suspension system using inertial delay control

In this paper an active suspension system is designed using inertial delay control for estimating the effect of uncertainties in suspension parameters, sprung mass variation and unknown road profile. The proposed control is designed with the objective of improving the ride comfort without having to use sensors for measuring the road profile or sensing the displacement and velocity of the unsprung mass. The design is validated by simulation for two road profiles and the performance is compared with passive suspension systems.
