Abstract
The paper proposes a new modeling method and active suspension control approach for elastic vehicles. While the vehicle designed lightly to get energy saving, it becomes flexible in nature. For obtaining the riding comfort and operation stability of elastic vehicles, there is a necessity to control vibration and motion. In this research, the modeling method calls as 'Extended Reduced Order Physical Model' is used to express vibration and motion of elastic body. A riding comfort and operation stability are improved using active suspension control designed by H∞ and sub-optimal control theories. Effectiveness of the control is demonstrated by simulation and experiment.
