Position Estimation and Parameter Identification of SynRM at Standstill

The purpose of this study was to construct a sensorless control system with parameter identification for a synchronous reluctance motor (SynRM). In this paper, initial position estimation and parameter identification at standstill are successfully demonstrated. A high-frequency voltage injection method was applied for initial position estimation and a recursive least squares (RLS) method was used for identification of the resistance and inductance, as well as the voltage drop caused by the inverter. The proposed system was examined experimentally and good results were obtained.
