Sammanfattning : This thesis deals with design and analysis of the control system structure for electric drives equipped with permanent-magnet synchronous motors with a salient rotor. The intended application is propulsion in electric- and hybrid-electric vehicles. LÄS MER
Sammanfattning : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. LÄS MER
Sammanfattning : To develop more competitive solutions, one of the trends in the development of drive systems for electric and hybrid electric vehicles (EVs/HEVs) is to integrate the power electronic converter and the electric motor. This thesis aims to investigate the performance and the operation of modular converters in integrated motor drive systems for EVs/HEVs. LÄS MER
Sammanfattning : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotiveapplications.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.
