The best place to work in the Global Automotive Industry. Join us on this exciting journey into the future, we want to hear from you!
Welcome to explore the world of Volvo Cars by writing your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable, and personal way – from day one!
Background
For Volvo cars, the future is electric meaning that all future drivelines contain at least one electrical machine. Since the cars are using batteries as the amount of energy in the car is limited and it is therefore important to also include energy efficiency in the optimization of the machine’s operation points. A common way to optimize the operating points for a machine is to use a numerical method to find what is called the maximum torque per ampere (MTPA) where the requested torque is achieved using the minimum amount of currents while still considering several constraints. However, the MTPA typically only considers steady-state operation and not the transitioning in between operation points. This part of the operation is of special interest in the case of induction machines as the time constant of the electrical and magnetic behaviors are greatly different.
Scope
The main objective is to investigate what an optimal operating strategy for the induction machine is including the transient operation (i.e. non-steady-states) for an automotive application. Optimal does in this case consider both energy usage and response rate of the electrical machine while considering the constraints imposed by the system and the operating point. Possible solutions to be investigated can be (but is not limited to) extend MTPA algorithm to include more than steady-state or introduce additional controllers for current or magnetization setup.
The work will mainly be done using Matlab/Simulink or another suitable simulation tool and if there is time in the then it may be possible to test the results in an electric machine rig.
What you´ll bring
We expect that the applying students have experience/studied electrical power engineering or engineering physics or similar. The student(s) is also expected to be present on site at Volvo Cars in Gothenburg during most of the thesis work, and any living arrangements needs be to be organized by the student(s).
Duration
