Abstract

This paper is concerned with the construction of an active suspension for a one-wheel car model by using fuzzy reasoning. The experimental model is approximately described by a nonlinear system with two degrees of freedom subject to excitation from a road profile. The active control at the suspension location is designed by using fuzzy reasoning based on single input rule modules, and it is constructed by actuating a pneumatic actuator with dead time. The performance degradation of the active suspension system due to the dead time of the pneumatic actuator is improved by inserting two kinds of compensators. The experimental result shows that the active suspension system with the compensators more improves the control performance than that without compensator.
