abstract
The vibrational control of a passenger car suspension system is addressed in this paper. A half-car model including passenger dynamics is adopted in the study Two robust control schemes are proposed, namely an inverse dynamics control scheme and a sliding mode control scheme. These controllers guarantee that the vertical and rotational displacements of the chassis converge to zero. In addition, the use of magnetorheological (MR) dampers located parallel to the suspension springs and shock absorbers is investigated. The simulation results of the controlled passenger car suspension system using MR dampers are very encouraging.
