Abstract: This paper is concerned with the active suspension design of one-wheel car models subject to excitation from a road profile using adaptive sliding mode control with the Variable Structure System (VSS) observer. The active control is composed of the equivalent and the switching controls, and the amplitude of the latter is adaptively changed according to the system performance. The active control force for the proposed suspension system is obtained by operating a pneumatic actuator due to the control signal that is computed by the measurement of the state variables for the car model. The experimental result indicates that the proposed active suspension system is relatively effective in the vibration suppression of the car model.

Keywords: active suspension systema; adaptive control; sliding mode control; pneumatic actuators; one-wheel car models; VSS observer; vibration suppression; sliding surface; compensator; road profile; variable structure system.
