On the Boundary Conditions in a Non-Linear Dissipative Observer for Tubular Reactors

Abstract

The modal injection mechanism ensures the exponential convergence of an observer in a continuous tubular reactor in dependence with the system parameters, the sensor location, and the observer gains. In this paper, it is shown that by simple considerations in the boundary conditions, the observer convergence is improved regardless of the presence of perturbations, the sensor locations acquire a meaningful physical meaning, and by simple numerical manipulations, the perturbations in the inflow can be numerically estimated.

“…Gutierrez-Carmona et al [4] analyze the performance of a nonlinear dissipative observer for a tubular reactor. They show that, by simple considerations in the boundary conditions, the observer's convergence is improved regardless of the presence of perturbations.…”
