ResumoA control algorithm is developed for active/semi-active suspensions which can provide more comfort and better handling simultaneously.A weighting parameter is tuned online which is derived from two components -slow and fast adaptation to assign weights to comfort and handling.After establishing through simulations that the proposed adaptive control algorithm can demonstrate a performance better than some controllers in prior-art, it is implemented on an actual vehicle (Cadillac STS) which is equipped with MR dampers and several sensors.The vehicle is tested on smooth and rough roads and over speed bumps.
