Automatic control of the simulated moving bed process for C8 aromatics separation using asymptotically exact input/output-linearization
Latin Abstract :
An approach to automatic control of the simulated moving bed process (SMB) applied to the separation of Cs aromatics is
presented. The principle of asymptotically exact input/output-linearization is used. The controller is based on a nonlinear state
estimator using the true moving bed model (TMB). The estimator receives measurement data from four spectroscopic measurement
cells. The problem of moving measurement positions with respect to the TMB model is addressed. An exactly linearizing feedback
of the estimated states is designed using the nonlinear TMB model equations. The performance of the controller is shown in
simulations using a detailed 5MB model as a representative of the real process.
