“…Interior permanent-magnet synchronous motors (IPMSMs) have received a great deal of attention in the field of automotive traction applications due to their unique features, such as high efficiency, high power density, and a wide constant power speed range [1]. The drive systems in these applications require strict torque regulation specifications that are less than ±5% of the rated value in the overall operating range [2].…”

This paper presents an online voltage disturbance estimator to achieve precise torque control of IPMSMs over a high speed operating region. The proposed design has a type of state-filter based on a Luenburger-style closed loop stator current vector observer. Utilizing the frequency response plot (FRF) approach, the estimation accuracy and the parameter sensitivities are analyzed. Accurate torque control and improved efficiency are provided with the decoupling of the effect of the parameter variations. The feasibility of the presented idea is verified by laboratory experiments.

“…Vector control of IPMSM were utilized by inducing the d, q command current based on the stator's voltage equation according to the IPMSM's field weakening control research reports in the 1990s [5,6]. Although, the field weakening control method made a significant contribution to establishing the basic field weakening theory, it requires an accurate value of d, q inductance for its high performance use.…”

-Interior permanent magnet synchronous motor is widening its application compared to other AC machines because of magnetic and reluctance torque. Despite of the advantages, improving control performance with parameter nonlinearity consideration is crucial during the field weakening control. This paper shows a maximum power control method at the field weakening region that considers d, q inductance's nonlinearity due to magnetic saturation and d, q mutual inductance. To verify the feasibility of control scheme, FEM simulations and experiments about comparison between linear and nonlinear maximum power control are carried out.

--This paper proposes a computationally efficient method based on imaging technique, for accurate prediction of 3-dimensional (3D) eddy current loss in the rotor magnets of interior permanent magnet (IPM) machines. 2D time-stepped finite element analysis is employed to generate the radial and the tangential 2D magnetic field information within the magnet for application of the 3D imaging technique. The method is validated with 3D time-stepped finite element analysis (FEA) for an 8 pole-18 slot IPM machine evaluating its resistance limited magnet loss with increase in axial and tangential segmentation. Magnet loss considering eddy current reaction at high frequencies is evaluated from the proposed method by employing the diffusion of the 2D magnetic field variation along the axial plane. The loss associated with all the frequencies together in the armature currents is evaluated by considering each of the harmonics separately in the proposed method employing the frozen permeability to account for magnetic saturation. The results obtained are verified with 3D FEA evaluating the magnet loss at fundamental, 10 and 20 kHz time harmonics in armature currents.Index Terms-Eddy current loss, finite element, frozen permeability, imaging method, permanent magnets.
