Lyapunov based nonlinear control of tubular chemical reactors ?

摘要

This paper is concerned with the stabilization of tubular reactors in which convection, dispersion, conduction phenomena as well as chemical reaction take place. The stabilization is performed by using a Lyapunov function derived from the second law of thermodynamics called availability function. This function is used to design a stabilizing distributed control law around a stationary profile of a tubular reactor driven far from the thermodynamic equilibrium. A numerical example illustrates the proposed control strategy.
