Vibration control of a semi-active suspension systems using model predictive control

초록

This study presents vibration control performance of model predictive control (MPC) for a quarter car suspension system equipped with a MR damper suffering from the saturation on damping force of MR damper. The MPC controller is designed and then applied to the suspension system to take into account the constraints associated with MR damper. The performance of MPC controller is compared to a conventional control method where the constraint of control input is handled by using a saturation function. The effectiveness of the MPC controller is evaluated by using bump excitation in time domain. © 2019 9th ECCOMAS Thematic Conference on Smart Structures and Materials, SMART 2019.
