Abstract
In this paper, the full-car model for passive suspension system (PSS), switchable damper suspension system (SDSS) and active suspension system (ASS) are compared in terms of their relative power requirements and ride performance. The linear quadratic regulator (LQR) and Fuzzy logic control (FLC) strategies are used for the system behavior and compared relative to the PSS. The PSS, SDSS, and ASS are evaluated in terms of ride performance criteria. The optimal suspension parameters values are evaluated. The results revealed that the ASS with the LQR control strategy gives better ride performance compared with PSS and SDSS. The ASS with the FLC strategy gives the best ride performance compared with the ASS using LQR control, and SDSS with LQR and FLC strategies.
