Mehroze IQBAL : "Design and control of hybrid electric vehicle for efficient urban use"

Abstract :This dissertation aims to develop an original and generic framework to synergize the design and control aspects in order to improve the prospects of hybrid electric vehicles (HEVs). The application is specifically depicted for the fuel cell variant of HEV (FCHEV). Special attention is given to urban environments because of their intermittent nature, which can have a negative impact on vehicle performance.
On the design side, specific vehicle parameters are utilized to size FCHEV powertrain components. Consequently, a unique baseline configuration is furnished, which is expected to provide consistent performance, but at the price of oversized sources. To overcome this, a novel concept of flexible design coefficients is introduced to assign an acceptable sizing range to sources. Then, the introduced coefficients are used to systematically coordinate sizing procedure with online energy management system (OEMS) of FCHEV.
At the control side, rules-based frequency separation method (FSM) is used as the standard OEMS, owing to its flexible online implementation. The applicability of a novel adaptive variant of FSM is explored. The proposed OEMS is tailored for consistent performance, with reciprocal awareness towards hydrogen consumption and sources degradation. For that, a concept of rationalized-cost and search-horizon based online optimizer is introduced to reach an insightful trade-off among the key optimization objectives.
The proposed coordinated approach is conceptual validated in the numerical simulations realized under MATLAB/Simulink. Several hypothetical driving cycles and a cycle with real driving data is extensively studied. The real-time applicability of proposed OEMS is also validated by an experimental test-bench with small-scale hybrid power system.
