Supplying proper voltage as an input, the MR fluid behavior will form a solid-state, controlling stiffness and damping in semi-active suspensions. Incorporating the benefits of active suspension and passive suspension, a semi-active suspension with an MR damper offers a mechanically simple, safe, and low power consumption solution. This study develops an extended fuzzy control strategy to improve ride control under road disturbances. To this aim, a quarter car model is adopted where the modified Bouc-Wen MR damper model is utilized to control damping force via a fuzzy control and a proportional-integral control. Several simulations are carried out with the designed controller under both bump and sinusoidal types of road disturbances. The merits of the proposed controller are compared with a classical fuzzy controller and uncontrolled case, wherein a significant improvement in reducing body displacement as well as suspension deflections is achieved. © 2021 IEEE.eninfo:eu-repo/semantics/closedAccessfuzzy controlmagnetorheological damperproportional-integral controlsemi-active suspensionConference Object10.1109/ISMSIT52890.2021.96045781411462-s2.0-85123276051N/A
