Abstract

The paper presents an extension of the mixed Sky-hook and ADD to Magneto-Rheological dampers. Firstly, a semi-active automotive suspension equipped with a nonlinear Magneto-Rheological damper is introduced. The interest of this nonlinear model is that the bi-viscous and hysteretic behaviors of MR dampers can be taken into account in the controller design. Hence, the designed controller is more adaptive with real MR dampers. Finally, the new mixed Sky-hook and ADD algorithm for MR dampers is proposed to enhance the passenger comfort. The performances of the proposed control method are then analyzed, based on simulations on a nonlinear vehicle model. The results show that the Mixed Sky-Hook and ADD can be successfully extended to Magneto-Rheological dampers.
