Abstract:
|
The energy management system of Diesel Hybrid Electric Vehicles allows the reduction of raw emissions
and fuel consumption by including them within the controller goals. With the forthcoming
Worldwide harmonized Light vehicles Testing Procedure (WLTP), the consideration of transient
pollutant emissions will constitute the only way of e ectively adhering to the emission regulations.
Particularly, the use of real time optimal control techniques will provide strategies which are both
implementable and achieve the best performance.
This thesis focuses on the use of optimal control theory to design causal energy management
strategies considering both NOx and soot transient pollutant emissions. An approach based on the
minimization of weighted fuel, stationary emissions and a penalty on the engine torque variation
is developed and solved using Stochastic Dynamic Programming (SDP) and an extended version
of Equivalent Consumption Minimization Strategy (ECMS). The resulting controllers are carefully
parametrized and tested over di erent conditions.
Both controllers result suitable for real time application, reducing the transient emissions over
unknown cycles. The introduced penalty shows a great potential for reducing transient emissions
for a low fuel increase, while requiring much lower computational resources than model-based
approaches. |
