Abstract
This study aims at designing a control system for an automotive active stabilizer in order to reduce the roll angle during cornering and 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 formulated. The control system for the active stabilizer is designed for the full vehicle model using the linear quadratic control theory. It is verified that the active stabilizer controlled by the control system designed is effective for both the roll reduction and the improvement of the ride comfort, although the passive stabilizer is only effective for reduction of the roll angle during cornering but makes the ride comfort of the vehicle worse.
