In this paper we present a structured approach to the modeling of an isotope separation plant that makes use of distillation principles for C13 isotope separation. In the first part of the paper, after a brief review of isotope separation processes with an accent on isotope separation by distillation, we define our initial-boundary-value problem, which is a partial differential equation. By applying...
Classic controllers are widely used in the hot rolling process in order to obtain seamless tube pipes. This process relies on heating up the billets inside a rotary hearth furnace (RHF). For the design of a classic positioning control system, of an unloading machine's arm that extracts the billets from the RHF, the authors used the Internal Model Control (IMC) method. The parameters used for tuning...
This article presents an automatic control structure for the unloading machine from a rotary furnace. In order to determine the movement pattern for the unloading arm the representation as an electro-hydraulic axis was used. The chosen control for this system is parameter scheduling, combined with optimal criteria, because it gave the best results in terms of time performances. The article presents...
