Βέλτιστος έλεγχος υβριδικού οχήματος κυψέλης καυσίμου (Bachelor thesis)

This Bsc thesis was developed in collaboration with the Process Systems Design and
Implementation lab (PSDI) of the Chemical Process and Energy Resources Institute
(CPERI) at the Center for Research and Technology-Hellas (CERTH).
The purpose of this work is to develop a framework to study the behavior of a Fuel Cell
Electric Vehicle (FCEV) and energy management strategies, and implement an optimal
control theory approach in the form of a Model Predictive Controller (MPC) that
governs both the power split and the operation of the FC. The studied system is
comprised of a Proton Exchange Membrane Fuel Cell (PEMFC), a Li-Ion battery, a
DC/DC converter and an electric motor fitted directly to the vehicle drive shaft. Using
mathematical models that describe the operation of the system and its components it is
possible to study its behavior under various operational scenarios and formulate
advanced control techniques.
In order to solve the optimization problem the method of nonlinear programming was
utilized, in the form of an Interior Point algorithm.
The thesis is structured around 8 chapters. Chapter 1 contains a brief overview of the
thesis in Greek, followed by the introduction in English in chapter 2, the literature
review (chapter 3), the description of the system in chapter 4, the development and
functionality of the heuristics controller (chapter 5), the formulation and operation of
the nonlinear model predictive controller in chapter 6, and finally the conclusions
(chapter 7) and the references in chapter 8.
