An experimental study of vehicle suspension semi-active control with skyhook controller and magneto-rheological dampers

摘要

The semi-active control algorithm for the vehicle independent suspension which equipped with magneto-rheological (MR) dampers is investigated in this paper. First, a quarter-vehicle suspension system model is established, and then a semi-active control algorithm based on skyhook damping control is designed. According to the demand of control algorithm, the MR dampers and corresponding sensors are installed on the test vehicle, and the road experiment is carried out with bump input. The experimental results show that the semi-active control algorithm can effectively improve the vehicle ride comfort.
