“…There are two mainly used object oriented modeling approaches for Multi-Domain systems, Kirchhoffians Networks [7] and Bond Graphs (BG) [8], [9]. Although both approaches are similar [10], in this work a BG model is developed, given the direct correspondence between the BG representation and the physical topology [11].…”

In this work the Multi-Domain model of an electric vehicle is developed. The electric domain model consists on the traction drive and allows including faults associated with stator winding. The thermal model is based on a spatial discretization. It receives the power dissipated in the electric domain, it interacts with the environment and provides the temperature distribution in the induction motor. The mechanical model is a half vehicle model. Given that all models are obtained using the same approach (Bond Graph) their integration becomes straightforward. This complete model allows simulating the whole system dynamics and the analysis of electrical/mechanical/thermal interaction. First, experimental results are aimed to validate the proposed model. Then, simulation results illustrate the interaction between the different domains and highlight the capability of including faults.

“…The physical meaning of each element is shown in Table 2.3. The models for several electric machines have been developed [80][81][82]. For example, a model for a BLDC PM motor was built using the MODELICA bond graph library in [80] as in Figure 2.23.…”

Modeling and dynamics analysis of electro-mechanical power-trains

In the past few decades, the electro-mechanical power-trains (EMPTs) are being used to replace the conventional power-trains in a few transportations, such as "More Electric Aircraft" and "Hybrid Electric Vehicle", to improve the energy efficiency and reduce greenhouse emissions. In the EMPTs, the electrical components such as electric machines, power electronics, controllers, and batteries are introduced. To accommodate these new components, the new power-train configurations are also involved. Due to the new components and new configurations, the application of the EMPTs gets a few challenges, including: (1) the nonlinear dynamics in the power-trains have not been sufficiently investigated, resulting in a limitation of the design optimization formulations that can reduce the vibration and noise levels in the power-trains; (2) the electro-mechanical interactions in an EMPT are not fully understood, especially the reflection of the vibration signature onto the stator current of electric machines. Therefore, the stator current has so far not been effectively utilized to analyze the dynamics and monitor the health of the EMPTs; and (3) modeling of the EMPTs is challenging and time consuming due to a large variation in the modeling strategies with respect to an EMPT's configuration and the intended research application. In other words, there is a lack of a modeling strategy that could be applicable to various types of the EMPTs and be implemented with relative ease.
