Abstract
The aim of this paper is the regulation of the temperature, at outlet conditions, for a class of plug flow chemical reactors. The considered reactor is modeled by a set of hyperbolic partial differential equations, as related to mass and energy balances, with consideration that the measured output for this kind of systems is the outlet temperature, as is usual with industrial practice. It is proposed that in nonlinear feedback which contains a proportional contribution of the named regulation error plus a high order sliding-mode term-to-tray to compensate for the convective transport, the nonlinear terms and disturbances employing the stabilizing effects of the sliding modes have a satisfactory performance. A theoretical frame for the stabilization properties of the proposed controller is provided and numerical simulations illustrate the corresponding performance, which is compared with a well tuned PI control law.
