A minimum-loss control strategy for the Dual-VSI-DFIG system was presented recently. Based on analytic optimization, three rules were derived for the optimal stator frequency, stator/rotor magnetizing current split and airgap-flux magnitude. These optimal rules were implemented via vector control using airgap-flux orientation. In this paper, the synthesis of the Proportional Integral controllers based on the symmetrical optimum criteria and the resulting stability are analyzed.

Abstract
A minimum-loss control strategy for the Dual-VSI-DFIG system was presented recently. Based on analytic optimization, three rules were derived for the optimal stator frequency, stator/rotor magnetizing current split and airgap-flux magnitude. These optimal rules were implemented via vector control using airgap-flux orientation. In this paper, the synthesis of the Proportional Integral controllers based on the symmetrical optimum criteria and the resulting stability are analyzed.File in questo prodotto:
