摘要：
In this paper a position sensorless control of a synchronous reluctance machine (SynRM) is discussed. The INFORM method is used to obtain the angular position information at low rotational speeds and standstill. By integration of current slope measurement into the pulse width pattern of the voltage source inverter a high position detection rate is reached at no additional accoustic noise compared to sensorless methods using voltage injection. At high rotational speeds an EMF model for SynRMs is presented and verified by experiments. Thus, a sensorless control of SynRMs in the complete speed range including standstill is implemented and offers an attractive and cost efficient electric drive solution for several applications.
