This paper deals with the identification of a synchronous machine parameter usefull for the purpose of sensorless and current control. Deviations from the steady-state voltage are generated by the current controller in order to drive the current to its desired value. In sensorless drives, voltage deviations from steady state are used in the case the back-EMF is too low to obtain an accurate rotor...
This paper deals with the rotor angle estimation for further Sensorless Field Oriented Control of Permanent Magnet Synchronous Machines using voltage Matrix Converters test vectors. The angle estimation is based on the machine saliency (difference between Ld and Lq), which is properly tracked by the application of pulse voltage test vectors. For all injection methods to function, some level of machine...
