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/sup /spl infin 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. >read more

State-space solutions to standard H/sub 2/ and H/sub infinity / control problems
TL;DR: In this article, simple state-space formulas are derived for all controllers solving the following standard H/sub infinity / problem: for a given number gamma > 0, find all controllers such that the H/ sub infinity / norm of the closed-loop transfer function is (strictly) less than gamma.
