Kinetic-Rotor Self-Commissioning of Synchronous Machines for Magnetic Model Identification With Online Adaptation

This article proposes a new magnetic model self-identification technique for synchronous machines to build the flux-map look-up tables. Provided the shaft is free to turn, an alternating self-acceleration and deceleration sequence is envisaged for identification without a dedicated experimental rig or additional hardware. With respect to previous works, the stator flux and the stator resistance are adapted online during the run, thus eliminating the need for postprocessing and the sensitivity to winding temperature variations during the test. Experimental validations on a 1.1-kW synchronous reluctance and a 11-kW permanent-magnet-assisted synchronous reluctance motors are provided.
