Abstract: Unique systems, methods, techniques and apparatuses of a synchronous reluctance machine (SynRM) control are disclosed. One exemplary embodiment is a control device structured to operate a converter coupled to a synchronous reluctance machine and receive measurements of current. The device comprises a converter controller structured to detect a power supply restoration, operate the converter so as to transmit a series voltage vectors relative to the stationary reference frame to the stator of the synchronous reluctance machine, receive current measurements following the transmission of each of the voltage vectors, estimate the rotor position using the characteristics of the voltage vector and the received current measurements corresponding to at least one voltage vector, estimate the rotor speed using the characteristics of the voltage vectors and the received current measurements corresponding to at least two voltage vectors, and operate the converter so as to apply voltage to the stator.
