Abstract
A three-way catalyst model ( ) and a method for modeling the dynamic response of a three-way catalyst that divides the catalyst response into sub-regions ( ) . A sub-model ( ) is constructed that represents each sub-region ( ) . Each sub-model ( ) is assigned unique attributes at which the sub-model is activated. The attributes are based on the system parameters and states. The states may be either continuous or discrete and define a hybrid state space. A larger or smaller number of sub-regions ( ) can be utilized based on the model's ( ) use and the accuracy desired for the model ( ).
