The design of suspension is very important for ride-comfort on automobiles. A lot of active and semi-active suspensions have been studied. In recent years, the car with active or semi-active suspension has been put into practice. Since the active suspension needs large power and space, a semi-active suspension have received attention. In this study, the bilinear disturbance accommodating control theory is established and it is applied to the semi-active control of suspension for automobiles. In this study, a 1/2 body model with 4-DOF is used. By applying the proposed bilinear disturbance accommodating optimal control to the semi-active suspension, its performance is investigated in the simulation. As a result, it showed better performance than the passive control with respect to the vertical acceleration and the pitch angular acceleration of the car body which influence ride-comfort for automobiles.
