The effectiveness of damping for SkyHook control strategy depending on how realistic damper model is

One of the most widely known control strategies for improving vehicle ride comfort is SkyHook, which was tested by many scientists. Those tests however were carried out mainly using simplified damper models with simple linear or two-linear, symmetric characteristics. On the base of real damper characteristics testing, the researchers in this article examined the influence of using more realistic and complicated damper models with friction, hysteresis and time-delay of state-switching implemented, on the effectiveness of control goals. They were measured by chosen dynamic responses of a suspension system for excitations in the typical exploitation frequency range. The results from the experiments were compared with those found in literature and with the simplified version of a damper model, without hysteresis, friction or actuation delay.
