Abstract

This paper compares pulsating and rotating vector carrier signal injection for self-sensing (or sensorless) control of PM synchronous machines. The main focus of the study is evaluation of estimation errors due to the physical non-ideal attributes of both the machine and the inverter. Initial position and magnet polarity estimation are analyzed as well. Transient response and signal processing for both techniques is discussed for completeness. The theoretical analysis is supported by experimental and simulation evidence obtained using interior PM synchronous machines.
