Abstract: This paper is concerned with the construction of an active suspension for one-wheel car models using fuzzy reasoning and dual dynamic vibration absorbers. The one-wheel car model with the dual dynamic vibration absorbers attached to the wheel part is approximately described by a non-linear system with four degrees of freedom subject to excitation from a road profile. The main purpose of the dual dynamic vibration absorbers is to improve the road holding of the wheel over a wide range of frequencies. The active control is determined by fuzzy reasoning based on the single-input rule modules because the car model is expressed as a complicated system and the control force is constructed by actuating the pneumatic actuator. The experimental result indicates that the proposed active suspension is significantly effective for the road holding of the wheel and also for the vibration suppression of the car body and the wheel part.
