“…Genetic algorithms are stochastic based search algorithms, widely used as optimization method for solving constrained/unconstrained, nondifferentiable, discontinuous or nonlinear problems [7], [9], [10], [17], [18]. The GA algorithm is inspired on the mechanics of natural selection, the process that drives biological evolution.…”

“…In 3Nm load torque OC1 provides around 2% more τ than the other strategies while in 24Nm it provides 13% more τ than ZDAC, 1% more than OC2 and 0.5% more than sinusoidal MTPA. The overall superior performance of OC1 is due to the significant magnitude of odd multiple of 3rd harmonics in PM flux linkage, whose can contribute in torque production when interacting with the respective current harmonics in OC1 [10]. The close τ performance of OC2 and sinusoidal MTPA can be associated to the fact that OC2 requires low magnitude of current harmonics not significantly impacting the current RMS value.…”

“…In [9], a genetic algorithm (GA) based method is employed to optimize the magnitude and phase of selected current harmonics in direct and quadrature axis in a PMSM with nonsinusoidal back electromotive force (back-EMF). In [10], a GA method is used to search an optimized current considering the zero sequence back-EMF harmonics to contribute in torque production. In these studies, the machine saturation and load effect on machine parameters are not taken into account in the current design, reducing the effectiveness of torque ripple mitigation https://doi.org/10.53316/sepoc2021.026 with minimum stator current magnitude requirement.…”

Permanent magnet synchronous motors with spatial harmonics can develop significant torque ripple under sinusoidal stator current feeding strategy. Usual approaches to reduce torque ripple aim the design of stator current harmonics, based on the machine electrical parameters, to induce compensating torque pulsations. However, the machine parameters are highly dependent on the electric load and the current harmonic content. Thus, these dependencies impose a challenge on the search for optimum stator currents. To overcome this drawback, this paper presents a genetic algorithm (GA) optimum current search procedure based on the machine design assisted by the Finite Element Method (FEM). Additionally, the variation of the onload estimated electrical parameters is analyzed considering different current feeding strategies. The results demonstrate that, according to FEM analysis, a null torque ripple with an increased torque per Ampère ratio is achieved and the parameter analysis demonstrates their different variation according to the current strategy.

There are several ways to reduce the ripple magnitude for direct torque-controlled permanent magnet synchronous motor (PMSM) drives. In this work, the compensated duty ratio optimized direct torque control (DDTC-TC) method was proposed to reduce the ripple for three-phase PMSM. The proposed control strategy employs the simplicity of conventional DTC (CDTC) and compensation of the reference torque to enforce the developed torque to oscillate around the required value. A torque error square minimization technique is employed to determine the duty ratio. The magnitude of the developed torque by the PMSM depends on the torque slope during the active and null voltage periods. The slope of the torque during each period is computed online. Based on the online computed slopes, the magnitude of the switching period and compensation torque were calculated. The ripple reduction capability of the proposed control scheme is tested using Matlab Simulink and a hardware in loop system. Results indicate that the control scheme is effective. Specifically, the torque and speed ripples are very small. The torque ripple during speed fluctuation is less for open-end winding PMSM. In addition, the proposed scheme is tested for four-quadrant operation, and the scheme is effective for four quadrant operation. Finally, verification of the effectiveness of the proposed scheme is performed using OPAL-RT-RT (OP4500). Verification indicates that the proposed scheme is effective.
