Field-Oriented Control of Permanent Magnet Synchronous Machine for Electric Traction Systems

This paper presents the implementation of a field-oriented control of a permanent magnet synchronous machine for electric traction systems. A low-scale prototype system was implemented using a dSPACE platform, which provides the computational resources for the implementation of the field-oriented control in a real-time application. Hall sensors and an incremental encoder were used for position measurement and a comparison was made between the performance of the field-oriented control in case of the two sensors. Also, the system efficiency was tested in case of a dynamic speed change scenario. Corresponding command signals, current signals and speed measurements are presented to validate the correct operation of the system.
