In this paper, a control system for an active stabilizer is designed in order to not only reduce the roll angle during cornering but also suppress the rolling vibration on a rough road concerning the ride comfort. A full vehicle model which has a suspension system with the active stabilizer is derived. The active stabilizer has an actuator which can actively generate the torque at the center of a stabilizer bar. In order to balance competing goals for the roll reduction and the improvement of the ride comfort, the control system for the active stabilizer is obtained using the linear quadratic control theory. It is verified that the control system designed can settle the rolling vibration on the rough road more quickly than the vehicle model of a normal suspension while reducing the steady roll angle during cornering to the same level as that of a passive stabilizer, and control the roll motion by the control torque which is lower than the reaction torque of the passive stabilizer.
