Abstract :
A quarter-car model of a hydraulic active suspension system is considered. This model has been constructed as an actual size test bed. A new controller design method based on H∞ control theory is proposed. Simulation and experimental results show that the controllers significantly attenuate the body acceleration gain of the closed-loop system in the range of human acceleration sensitivity. The controllers are also robust against changes of the body mass and system damping
