“…Efficient suppression of back-emf caused current harmonics requires their quick and accurate detection from the stator currents, which in turn calls for precise current measurement. Proposed approach relies on oversampling and PWM averaging [14], followed by extraction of individual harmonics by one-fundamental-period averaging in multiple reference frames [13].…”

“…Within this box, E αβ represents the electromotive force of the controlled motor, acting as the voltage disturbance. Sum of external voltage signals U k αβ , k ∈ [5,7,11,13,17,19], k being the harmonic number of any relevant harmonic, is added to the voltage command U αβ in order to suppress the current harmonics. The signals U k αβ are obtained from individual harmonic controllers.…”

“…The combination of back-emf harmonics [12] and relatively low phase impedance gives rise to non-negligible amplitudes of undesired phase current harmonics, which cause acoustic noise and the torque ripple [1], [13]. If these harmonics remain unaccounted for, the drive is not suitable for applications with strict requirements on vibrations, torque ripple and noise.…”

<div>Abstract—This paper introduces a novel algorithm for suppresion of phase current harmonics in three-phase brushless dc motors caused by non-ideal back-emf waveform and dead-time effects. Proposed feedback acquisition chain obtains an exact information on all the relevant harmonics within each period of the fundamental. Design of the harmonic regulator based on the internal model control principle is given. The paper outlines the relevant details of implementation and the results of verification performed by both computer simulations and experimentally, using a laboratory prototype machine. Experimental results conducted in presence of non-sinusoidal back-emf and with erroneous dead time compensation prove the ability of the proposed solution to remove the stator current harmonics quickly, in just two fundamental periods.</div>

“…The motivation of their use is often associated to their higher power density and higher efficiency compared to DC or induction motors [3], [4]. Due to design guidelines or mechanical tolerances during manufacturing process, the PMSMs may suffer from spatial harmonics on PM flux linkage and stator inductances [5], [6]. Conventional control schemes which neglect the harmonic content may produce reasonable torque ripple level, which is undesirable in high-performance motion control because it is associated to the increase of vibration, speed undulation and mechanical wear and tear on mechanical drive parts, hence reducing the life of the system [7].…”

Permanent Magnet Synchronous Motors (PMSMs) may present spatial harmonics depending on the design guidelines or imprecisions on the manufacturing process. The interaction of conventional sinusoidal current feeding strategies with these spatial harmonics can produce a considerable torque ripple. This paper deals with a modified Finite Control-Set Model Predictive Torque Control (FCS-MPTC) loop as an active torque ripple minimization solution for PMSMs with spatial harmonics. The proposed approach designs a novel cost function, based on the cross product reactive instantaneous power theory. The benefits of the proposed generalized approach include providing smooth torque production and the Maximum Torque per Ampère (MTPA) operation on PMSMs with a number of spatial harmonic sources, including those on zero-sequence. The effectiveness of the presented control strategy is demonstrated comparatively to conventional sinusoidal current feeding strategy on a PMSM drive employing a three-phase four-leg two level voltage source inverter under both steady and transient state.
