Commissioning and Sensorless Control of High Power SyR Machine Prototypes

This work deals with parameters identification of high power/ high current prototype of synchronous reluctance motor (250~kW). Both the converter and motor parameters are retrieved in a complete commissioning procedure. The obtained parameters are adopted for implementing a proper sensorless control strategy. The relevant size of the drive imposes several implementation issues and constrains, including the low switching frequency, that must be taken into account. Moreover, the machine presents very high harmonic distortion, deeply affecting the control.
