Modelling and numerical simulation of the dynamic behaviour of three way catalytic converters

The improvement in computational power has allowed researchers to model and simulate dynamical systems of growing complexity. In particular, we report on the construction of a reference model to be used as a workbench to design and test control strategies aimed at minimizing the global emission of three-way catalytic converters (TWC) in non-steady-state conditions. This problem is of great interest to industrial application since vehicle emission standards are becoming stricter, and a detailed mathematical description of TWC is thus necessary for the optimization of its performance. In this perspective, we also present a reduced order model for the purpose of real-time implementation
