Abstract

This paper presents a model-based control method for transportation control of a rectangular tank, considering the suppression of sloshing, i.e. liquid oscillations. Sloshing phenomena as caused by horizontal motion are analysed by means of a 2D distributed parameter model and a modal model. The latter is used for generating an optimal open-loop control input which reduces sloshing and provides savings in total transportation time. Furthermore, H^∞ feedback control is incorporated in the neighborhood of the target location, in case more precise control is needed. Key points for transportation control of a cart-based rectangular tank are clarified
