Development on a test model of algorithms control of synchronous reluctance machine

The test model of a synchronous reluctance machine, with anisotropic magnetic conductivity of the rotor, designed earlier in C++ on the basis of calculations in ANSYS Maxwell, is supplemented with new control algorithms for evaluating the characteristics of electric drives. Two-zone vector control is realized. In the zone of low rotational frequencies the current vector shift relative to the cross axis of the rotor is constant, and the current amplitude is controlled. At higher frequencies the current vector shift relative to the cross axis is reduced modulo limit the stator voltage. The algorithms of emergency and smooth reversal of the rotor are considered, and smooth reversal is recommended. At smooth reversal the sign of the angle of current vector shift relative to the transverse axis of the rotor changes in the zone of small currents. On personal computers calculations on the test model are performed in real time, which is ensured by using the methodology of modeling systems by interconnected subsystems.
