Self-Commissioning of Synchronous Reluctance Motor Drives: Magnetic Model Identification with Online Adaptation

A new magnetic model self-identification technique is proposed to build the flux-map look-up tables (LUTs) for synchronous reluctance (SyR) machines. Provided the shaft is free to turn, an alternating acceleration and deceleration sequence is envisaged for identification without a dedicated experimental rig or additional hardware. Respect to previous works, the stator flux and the stator resistance are adapted online during the run, thus eliminating the need for post-processing and the sensitivity to winding temperature variations during the test. Experimental validation on a 1.1 kW SyR motor test-bench shows promising results.
