Abstract :
This paper analyzes the effects of the transient resistances in saliency tracking-based sensorless control methods of PM synchronous machines. A high frequency model of the PM synchronous machine including both stator and rotor transient resistance is presented. From this model, potential sources of error in the estimated position due to the transient resistances are analyzed, and their compensation by means of an adaptive decoupling mechanism is proposed. The paper also addresses the influence and compensation of temperature effects in carrier signal injection-based sensorless techniques.
