Control of the temperature distribution in two dimensional space of an annular type non-isothermal adsorber

摘要

A new annular-type non-isothermal adsorber is proposed, which makes it possible to separate a multi-components gas mixture continuously. For the effective operation of the adsorber, it is essential to control the temperature distribution in the two dimensional space (axial and angular direction) of the adsorber. In this work, the controller design is based on a method reducing distributed parameter system (DPS) to lumped parameter system (LPS) through the eigenfunction expansion. The advantage of this method is that the design of the feedback controller is very simple because the reduced LPS model is completely decoupled. The results show that the whole temperature distribution in the adsorber is estimated accurately from several measurements by using the Kalman filter as an observer. The designed servo controllers' performances are satisfactory in spite of using the reduced order LPS model. (C) 2003 Elsevier Ltd. All rights reserved. [References: 10]
