6. Highly Dynamic Drives for Electric Hybrid Vehicles : Electric Machine Design and Dynamic Test Method
Sammanfattning : Electric Hybrid Vehicles (EHVs) play a crucial role in the development towardsa more environmental friendly transportation. An alternative to solve someactual challenges with hybridization of vehicles is studied at the Division ofIndustrial Electrical Engineering and Automation (IEA) at Lund Universityin cooperation with the automotive industry.

7. Control of permanent-magnet synchronous machines in automotive applications
Sammanfattning : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotive applications. Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly. LÄS MER
8. FEM Analysis Applied to Electric Machines for Electric Vehicles
Sammanfattning : Electric vehicle technology is an interdisciplinary field in continuous development. It appears to be a margin for improvements. The Division for Electricity at Uppsala University is doing significant research in the field. The present thesis investigates electric machines for vehicular applications, both in the driveline and in the traction motor. LÄS MER
9. Technology for biocomputational devices based on molecular motors
Sammanfattning : For many multivariable problems there are no efficient algorithms for finding solutions. To this day, conventional electronic computers mainly solve problems in a sequential manner. This sequential operation prevents problem-solving within a reasonable time-frame due to superpolynomial, and sometimes even exponential, time complexities. LÄS MER
10. Power loss minimization in electric cars by wheel force allocation
Sammanfattning : The need for lowering the emission levels has never been greater than now. In the vehicle industry, electrification seems to be an irreversible way ahead but user-related challenges such as limited range delay electricity as the primary energy source for personal transportation.
