Abstract :
New results have shown good performance in comfort or road holding of on/off control strategies for automotive semi-active suspension systems. Even tough, there are not optimal solutions for both goals simultaneously. A Frequency Estimation Based (FEB) controller that exploits the full damping variation of an Magneto-Rheological (MR) damper is proposed. This controller adapts its output according to several frequency bandwidths. A comparison with three commercial controllers is included based on a Hardware-in-the-Loop (HiL) approach. The FEB controller outperforms the benchmarks control strategies by 11.2 % in comfort. For road holding all strategies are similar; however, FEB controller works better for both goal simultaneously.
