2. Control of permanent-magnet synchronous machines in automotive applications
Abstract : 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. READ MORE

5. On design and analysis of synchronous permanent magnet machines for field-weakening operation in hybrid electric vehicles
Abstract : A regular vehicle of today is equipped with an internal combustion engine that runs on either gasoline or diesel, which are fossil fuels from oil reserves that are millions of years old. In all types of combustion processes carbon dioxide and several other emissions are produced. READ MORE
