Decoupled d-q Model of Double-Star Interior-Permanent-Magnet Synchronous Machines

TL;DR: A d-q transformation to be applied to double-star permanent-magnet synchronous machines with interior magnets that agrees remarkably well with the experimental results and FE simulations.

Two Alternative Modeling Approaches for the Evaluation of Wind Farm Active and Reactive Power Performances

TL;DR: Based on the stator-flux-oriented electromechanical model of a doubly fed induction machine (DFIM), two different approaches to wind farm modeling are presented in this paper, where the overall control system of the DFIM is modeled in detail, so that tuning equations that allow adjusting the parameters of its proportional integral compensators straightforwardly are provided.

Low-Speed Control Improvements for a Two-Level Five-Phase Inverter-Fed Induction Machine Using Classic Direct Torque Control

TL;DR: It can be observed that the proposed technique can significantly improve the rate of change of stator flux, the torque response, and the speed response compared with traditional method.

Impact of Cross-Saturation in Sensorless Control of Transverse-Laminated

TL;DR: The robustness against cross-saturation is shown, in practice, and the obtained drive performance is pointed out proving to be effective for a general-purpose application.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors

TL;DR: In this paper, the impact of the amplitude of the carrier voltage is pointed out, leading to a mixed (carrier injection plus electromotive force estimation) control scheme, with a commercial transverse-laminated SyR motor.
