摘要

The magnetorheological fluid (MRF) damper is a crucial component for vibration suppression and has been widely applied in vehicle suspension systems. However, the nonlinear characteristics and the dead zone of the MRF damper are pronounced, which decreases the effectiveness of the control performance. This work proposes a novel bumpless switching fuzzy control (BSFC) strategy to enhance the effectiveness of vibration suppression in the semi-active suspension (SAS) system equipped with the MRF damper. First, the nonlinear characteristics of the MRF damper are approximated by the Takagi–Sugeno (T-S) fuzzy method. Meanwhile, an adaptive observer is designed to reduce the measurement cost of the proposed BSFC controller. Finally, a quarter-car test rig is constructed to examine the effectiveness of the proposed BSFC controller according to dynamic indexes including suspension deflection (SD), tire deflection (TD), and acceleration of sprung mass (SMA). The results demonstrate that the designed controller exhibits significant advantages in vibration suppression, stability enhancement, and disturbance rejection.
