Control Algorithms for Permanent Magnet Synchronous Traction Motor

The paper deals with research of sturdy control algorithm for traction drive with permanent magnet synchronous motor (PMSM). Two design algorithms are described here. First algorithm is control of phase currents which are based on control of instantaneous value of current for all phases of motor. Second algorithm is represented by control of phase currents in d-q frame (Field Oriented Control). The algorithms, which are mentioned above, are compared in this paper. Simulations results of both algorithms and partial results from measurement of traction motor with PMSM are cited in this paper, too. The traction motor with nominal power 58 kW makes use of phase currents control.
