According to a recent general asymmetric hysteresis model proposed by the author, this paper studies the semi-active control of MR dampers in automotive damping applications.The proposed asymmetric hysteresis loop model of MR dampers In the “one-quarter” two-degree-of-freedom automobile model, the “empty” control law is used to automatically adjust the damping force of the MR damper. The simulation results verify that the damping force asymmetry and hysteresis characteristics , And shows that the complexity of the designed semi-active nonlinear controller is greatly reduced and the ideal damping performance of the automobile suspension is achieved
