The active suspension required energy input levels and the high component costs. In this work, the Limited bandwidth hydro-pneumatic active suspension (LBA) is used and it has all the advantages of active system except that the actuator is limited at 6 Hz bandwidth, thus making it economical on power consumption and cost. The aim of this study is to develop four degrees of freedom (DOF) half vehicle model including the Limited-Bandwidth hydro-pneumatic active suspension system. The LQR and Fuzzy Logic Control (FLC) are used to evaluate the vehicle ride performance for Limited bandwidth hydro-pneumatic active suspension. The result indicated that the limited-bandwidth Hydro-pneumatic active suspension with LQR gives better ride performance compared with the passive suspension system. On the other hand, the FLC improved the vehicle ride performance in terms of front and rear body acceleration by 4% and 7.5% respectively compared with limited-bandwidth Hydro-pneumatic with LQR. The power demand for limited-bandwidth Hydro-pneumatic with LQR and FLC are evaluated and discussed.
