| Résumé : |
In order to design efficient hybrid vehicle drivetrains, FlandersMake, a strategic technological research center, need adequate models to support the decision making process. Because the model is dedicated to be used in a chain of several models (Gearbox, thermal motor, wheels, ...), the main requirement is the fastness. Our work has been to design such models of electrical motors. Moreover, it has to be highly parameter-ized so there will be no need to build a new model for each different topology of motor. As the accurateness must still be satisfying, the model has to take in account the non-linearity of the magnetic material. Modeling of Electrical Machines (EMs) is often carried out using numerical techniques, such as finite element analysis (FEA). Although FEA is capable of modeling EMs with a high level of fidelity, it has several disadvantages, such as the huge computational time and memory usage. These drawbacks make the use of FEA is not preferred in hybrid vehicle design, which requires a lot of iterations during the optimization process especially in early design stages. On the other hand, the Magnetic Equivalent Circuit (MEC) method is well suited for this purpose and fit our needs. The approach is simply based on representing an EM with a magnetic reluctance network that depends on machine geometrical parameters and material properties. In addition, a proper ‘low-level’ control model is essential to design an algorithm to maximize the overall drivetrain efficiency. We will use a field-oriented control approach (field-weakening theorem) to control those EMs. The goal of this Master thesis is to develop a Matlab-based generic and parameterized MEC for two types of radial EMs, namely SRM (Switched Reluctance Machine) and IM (Induction Machine). Lucien Mine will work on IM's and Nicolas Heindryckx on SRM's. Thanks to those models, a comparative analysis can be done between the aforementioned EMs to check the most appropriate EM for the three main hybrid vehicle topologies, i.e. series, parallel, and series-parallel. The hybrid system model and the energy management control technique, using for example dynamic programing, will be provided by Flanders Make. |
