Adaptive Control of Axial Dispersion Non Isothermal Tubular Reactor: A Nonlinear Model

This paper propose a relatively simple adaptive control (in the presence of input constraints) for a class of nonlinear distributed parameter models with application to a nonisothermal exothermic chemical tubular reactor with axial dispersion. Our objective is to regulate the reaction temperature in a prespecified neighborhood of a given reference temperature. we apply a λ-tracking controller, only little information on the systems is needed to show that the tracking error tends asymptotically to a ball centred at the reference temperature and of arbitrary prescribed radius λ > 0.
