Availability based Stabilization of Tubular Chemical Reactors

This paper is concerned with the stabilization of tubular reactors by using the second law of Thermodynamics. The thermodynamic availability function is used as a Lyapunov function for the practical derivation of distributed control laws for the stabilization around a stationary profile of a fixed bed reactor. No assumption is made on the linearity of phenomenological law as for linear irreversible thermodynamics neither on the passivity of the considered system.
