Combined Feedforward/Model Predictive Tracking Control Design for Nonlinear Diffusion-Convection-Reaction-Systems

Abstract : The tracking control design for setpoint transitions of a quasi-linear diffusion-convection-reaction system with boundary control is considered. For this a suitable model-based feedforward control is determined that relies on the flatness-based parametrization of the control input. A receding horizon feedback control is added within a two-degrees-of-freedom control scheme to account for disturbances, model inaccuracies, and input constraints.The tracking performance of this control scheme is shown by means of simulation studies.
