FIRST PRINCIPLES INVARIANTS FOR ASYMPTOTIC OBSERVERS IN CHEMICAL REACTORS

In this paper, a method to build asymptotic estimators for continuous stirred tank reactor in the case of constant pressure and constant volume liquid phase is proposed. The estimator is based on the measurement of temperature and some concentrations. This method works for highly nonlinear reactions, with realistic thermodynamic properties and is based on the preservation of two fundamental conserved quantities: the mass and the energy. Simulations results for an example are proposed and discussed.
