| Abstract |
The multi-converter multi-machine systems as the extensions of the classical drives present several
structures, as the mono-inverter dual motor system working with a common mechanical load. In
traction applications the necessity to provide an excellent torque response is primordial. As a
consequence, in order to control each motor torque production of this kind of structures especial
methodologies based on the classical Field Oriented Control (FOC) can be applied.
This paper deals with the description and simulation of four different control structures for monoinverter
dual induction motor systems. A briefly description of the modelled high power system,
representing a commercial locomotive is presented. The electromagnetic motor information needed by
the FOC is reconstructed using a deterministic rotor flux observer, where its gain coefficients had
assigned applying a very simple and efficient method. The principle of four control methodologies are
discussed and analysed. Two mechanical perturbations have applied to the system: the adherence lost
of one wheel and the stick-slip perturbation. The system working responses obtained by simulation are
compared, establishing the principal differences between the four proposed control methods. |
