Modelling and state observation of Simulated Moving Bed processes based on an explicit functional wave form description

Efficient Moving Horizon State and Parameter Estimation for the Varicol SMB Process

“…In the literature, relatively few contributions that deal with state estimation of SMB processes can be found. The published work is based upon the approximation of the concentration profiles by a set of truncated exponential functions Alamir and Corriou (2003), or by using the equivalent True Moving Bed (TMB) model Mangold et al (1994), Kloppenburg and Gilles (1999), or deals with the engineering of tailored estimation schemes Küpper and Engell (2006), Kleinert and Lunze (2005). Recently, a rigorous moving horizon estimation approach for SMB processes was proposed by Küpper et al (2009).…”

An Adaptive Control Concept for Simulated Moving Bed Plants in Case of Complete Separation

“…First approaches on control designs using low order models can be found in work by Schramm et al [2] and Kleinert and Lunze [5]. These make use of the movement of the concentration fronts in a different manner.…”

An Adaptive Control Concept for Simulated Moving Bed Plants under Reduced Purity Requirements

“…The natural question arises if it would be possible to describe the essential dynamics with a low-order model. First concepts with this philosophy are published in [2] and [5]. They used various simple models to describe the movement of the concentration fronts.…”
