Abstract Details

2020, Doctor of Philosophy, Ohio State University, Mechanical Engineering.
Today’s world faces numerous environmental challenges as we attempt to meet the growing demands for mobility while tackling its negative externalities. In recognition of these negative externalities, world governments have enacted increasingly stricter standards that the means of mobility must meet. To meet these demands, private and public industries have invested tremendous resources into alternative means of mobility. The most promising step to immediately reduce mobility’s negative externalities is the use of hybrid technologies. Hybrid technologies utilizes traditional petrochemical energy sources combined with electrical sources to power mobility. If properly controlled, this allows for a reduction in energy consumption and pollutant production in vehicles. The challenge for mobility engineers is how to properly control these multi-domain systems to reduce negative externalities. Extensive research in the field of optimal control applied to hybrid vehicles has already shown that fuel consumption can be minimized within a charge sustaining hybrid through optimized torque splitting. Furthermore, research into pollutant production and control has greatly reduced air pollution from vehicles. Both fields have already penetrated the consumer market and helped form control strategies that are already on the road. However, the increasing demands placed by regulations require constantly pushing the bounds for the extra reduction in fuel consumption or pollutant production. As such, this research develops a methodology that can be applied to HEVs to establish a controls strategy for the simultaneous reduction of fuel consumption and pollutant production. This work relies on model-based techniques to simulate vehicle operation, and optimal control techniques to use the developed vehicle models to establish control policies to reduce fuel consumption and pollution production. This work goes through the development of a catalyst and emissions model that predicts tailpipe emissions based on oxygens storage dominate three-way catalyst models. A methodology is presented including the experimental work needed to develop such a model. This is combined with a vehicle energy model and optimal control algorithm. With the combined plant, an optimal control problem is formulated and solved with control techniques to develop control policies that allow for reductions in fuel consumption and pollutant production. Finally, this work is completed under the constraints of real-time implementation with the intent of application in a model predictive controller.
