Abstract: This paper presents the construction of an active suspension system for a quarter car model using fuzzy reasoning. The active control is obtained as a weighted sum of the defuzzificated values of the outputs in single input rule modules, and is generated by using a pneumatic actuator. The experimental result indicates that the proposed active control is more effective in the vibration isolation of the vehicle body than the skyhook damper and passive controls.

Keywords: active suspension system; fuzzy reasoning; single input rule modules; pneumatic actuator; quarter car model.
