Damping Control of Liquid Container on a Carrier with Dual Swing-Type Active Vibration Reducer

摘要

This paper presents a damping control of a liquid container with an active vibration reducer on a wheeled mobile robot. The active vibration reducer independently tilts the liquid container to running direction and transverse direction. The optimal servo control system is adopted as a damping control of liquid sloshing with the vibration reducer. A Kalman-filter is used to estimate states and remove noise of sensors. An input shaping method is applied to design damping paths of mobile robots. The damping performance is more improved by using the vibration reducer together with the damping path design. The usefulness of the proposed method is demonstrated through simulation and experimental results.
