Abstract:
On the basis of the generalized asymmetric hysteresis model which has recently been proposed by the authors, this paper deals with sem-i active control for the vehicle suspension vibration attenuation by employing a sem-i actively controllable magneto- rheological (MR) fluid damper. The proposed asymmetric model of an MR- damper is employed in a 2-DOF“ quarter- car” model, and the “ skyhook” control law is applied to implement variable damping deduced from theMR- damper. The simulation results demonstrate the contributions of damping asymmetry and hysteresis in response to the sem-i active suspension, and suggest that the sem-i active nonlinear controller synthesis can be greatly simplified to achieve superior vibration attenuation performance of the vehicle suspension.
