Abstract

This paper deals with vibration control of a wheeled vehicle running over an irregular terrain. The following four control metheds mainly utilizing future terrain information are considered. (1) Whole preview control methed utilizing present and future terrain information; (2) Partial preview control method utilizing present (all wheel's) and future (only rear wheel's) terrain information; (3) Feedforward compensation control methed utilizing only present terrain information; (4) Feedback control methed utilizing no future terrain information. In the simulation studies, it is shown that position control and vibration control are much improved by utilizing future terrain information.
