Abstract

This paper proposes a method to diagnose unexpected changes in the dynamic behavior of Chemical Reaction Network models. It is considered that the disturbances can induce changes in the reaction rate coefficients of chemical reactions. Conditions for the estimation of such disturbances are formulated. Using the algebraic properties of kinetic models, on-line observers are designed to monitor the disturbance-generated modifications in the reaction rate coefficients. An extended disturbance observer is also introduced for such cases when not all the states of the Chemical Reaction Network are measurable. The applicability of the developed method is shown through simulation studies.
