Robust stabilization of running self-sustaining two-wheeled vehicle with varying speed and mass variations

This paper deals with robust stabilization of running self-sustaining two-wheeled vehicle with varying running speed and mass variations. Recently, there have been a lot of research results about stabilization of two-wheeled vehicle. These researches have achieved the stable running only by the steering control. However, an actual two-wheeled vehicle is stabilized by not only the steering control, but the control of a vehicle's center of gravity. We have proposed the stabilization control method of two-wheeled vehicle in the state of stillness, and have shown the effectiveness of proposed approach. In this research, we construct the control system for the running stabilization of two-wheeled vehicle. H^∞ control problem is used to design the controller to achieve running stability even if the running speed and the mass of two-wheeled vehicle would change. The experimental results show effectiveness of proposed approach for robustness.
