Robust Control of a Pressure Swing Adsorption Process

Abstract This paper presents the H ∞ control of a pressure swing adsorption process. This separation process is characterized by periodic operations. The objective of the control is to assign the trajectory of some concentrations and to reject the perturbation on the inlet composition. The control design is synthetized from some Hammerstein model that approximates the cyclic process. The control scheme is designed using H ∞ optimization method. J -spectral factorization is applied to derive the controller. The controller is then validated both on the Hammerstein and complete models. Simulation results are given. Comparison with PI controller is done.
