Identifiability Analysis of a Liquid-Liquid Phase-Transfer Catalyzed Reaction System

Identifiability is a structural property of mathematical models. A model is identifiable if the model parameters can be uniquely identified from input-output behaviour. This work focuses on the application of a novel methodology for testing differential algebraic equation systems for identifiability. In this work, a non-linear, differential algebraic model of a liquid-liquid phase-transfer reactor is tested for identifiability using a linearization-based approach. This approach is shown to be useful for the testing of identifiability even for inherently non-linear models. Furthermore, this approach allows the effect of system parameters on the non-linear system to be qualitatively analyzed.
