Resumen
In this paper, a flux weakening control strategy based on a vector space decomposition (VSD) model is presented for asymmetrical dual threephase interior permanent magnet synchronous machines (IPMSMs). This strategy incorporates a voltage magnitude feedback loop, which provides robustness by adding a variation to the actual speed when enters in flux weakening mode or deviations occur in the electrical parameters of the machine. Validity of the proposal is demonstrated by simulation results carried out over standardised driving cycles, taking into account parameter mismatches.
