TLDR
It is observed that the MR damper suspension systems with optimal parameters perform an order of magnitude better than the passive suspension and perform as well as active suspensions with limited state feedback, and closer to the performance of fully active suspensions.Abstract:
In this paper, control of the stationary response of a half-car model with a magnetorheological (MR) damper moving over a random road is considered. The MR damper is characterized using Bingham and...read more

Optimal semi-active preview control response of a half car vehicle model with magnetorheological damper
TL;DR: In this paper, a half car model with magnetorheological dampers is modelled by the modified Bouc-Wen model and the MR damper performance is sought to be improved by suitable choice of input currents to the levels of performance of an active suspension based on H ∞ control without and with preview.

An innovative magnetorheological damper for automotive suspension: from design to experimental characterization
TL;DR: In this paper, a completely new magnetorheological fluid (MRF) damper model is proposed for semi-active control of automotive suspensions. But, unlike the conventional solutions where the coil axis is usually superposed on the damper axis and where the inner cylindrical housing is part of the magnetic circuit, the coils are wound in a direction perpendicular to the dampers axis.
