“…Further, it is explicitly mentioned that the current control loop (using a PI controller) is accomplished through FOC. Overshoot in the stator current due to changes in the speed/load has affected PMSM drives, however, many approaches have been presented to address this issue (Basnet and Pillay, 2021; Zhao et al , 2021; Zhou et al , 2022; Yi et al , 2022). The minimizing of torque ripples is one such method, and it falls into two different subclasses.…”

“…However, these methods have limitations, such as raising the complexity of motor development, manufacture and subsequently expense. Torque ripples are another issue; thus, the second group is concerned with controlling PMSM drives to minimize them (Zhou et al , 2022; Yi et al , 2022). Additionally, stator current ripple is exactly related to torque ripple, therefore, lowering stator current ripple will also lower torque ripple.…”

Purpose This paper aims to present a cascaded pseudo derivative feedback (PDF) plus pseudo derivative feedback plus pseudo derivative feedforward (PDFF) controller for a permanent magnet synchronous motor (PMSM) to improve the transient response of the system. Design/methodology/approach Proportional integral (PI) plus PI controller and the proposed PDF plus PDFF controller are designed, stability analysis is performed using the extended root locus method, and the effect of the damping coefficient is also extensively studied to validate the robustness of the proposed controller. Findings When compared to a cascaded PI plus PI controller, the proposed control approach has a much shorter settling time for the entire system and a 50% reduction in overshoot in stator current under extensive variations in speed with load disturbance. Originality/value The proposed controller is programmed into an FPGA Altera Cyclone II and applied to a 1.5 kW laboratory prototype PMSM drive. The effectiveness of the proposed methods has been demonstrated experimentally throughout a wide variable speed range, from 0 to 157 rad/s at different load conditions.

“…Subsequently, the PM EC loss can be studied based on the theory of air-gap magnetic field modulation. Currently, more and more scholars are focusing on air-gap magnetic field modulation theory [10], [11], [12], [13], [14], [15]. Reference [9] investigates the PM EC loss in two different kinds of flux-switching machines.…”

This paper investigates the permanent-magnet (PM) eddy current (EC) loss in a spoketype flux-modulation (STFM) machine with inverted T-shaped permanent magnets. The key is to design appropriate flux barriers in such rotor structures to suppress the PM EC loss with little effect on torque performance. First, the main harmonic orders generating PM EC loss are analyzed based on the air-gap magnetic field modulation. The findings indicate that some non-working harmonics produce PM EC loss, which can be suppressed by reducing these harmonics. And the proportion of PM EC loss produced by these harmonics is calculated through the analysis of a three-dimensional model of PM EC loss. Then, a new rotor structure with flux barriers is proposed to suppress PM EC loss based on ensuring the torque performance by reducing the 1st-order harmonic. Finally, the electromagnetic performance of the two machines is compared by finite element analysis. Stress analysis and temperature distribution simulation are also carried out to prove the feasibility of this structure. The results show that the proposed structure is effective in suppressing PM EC loss with little influence on the main electromagnetic performance.INDEX TERMS Air-gap magnetic field modulation, harmonic analysis, magnetic flux barrier, PM EC loss.
