Abstract: Aiming at the torque ripple problem of direct torque control that is based on space vector pulse width modulation (SVPWM-DTC) caused by the spatial harmonics and magnetic saturation characteristics of permanent magnet synchronous motor (PMSM), a feedforward controller based on an analytical model of PMSM was designed. An analytical motor model taking the spatial harmonics and magnetic saturation characteristics of PMSM into account by reconstructing the numerical solution of magnetic co-energy (MCE) from finit… Show more

“…The number of pole pairs in a mechanical motor with a speed of 2000 rpm is 3, and 12th harmonics frequency is 1.2 kHz. The proposed GEO-ANFIS achieves less torque ripple of 0.44 Nm, which is better than the existing HWOA [16], SVPWM-DTC [21] and ANFIS which attained 1.62, 0.60 and 0.53 Nm respectively. Fig.…”

“…Table 5 shows the comparison of torque ripple. From Table 5, it clearly shows that the proposed GEO-ANFIS achieves less torque ripple over the existing HWOA [16], SVPWM-DTC [21] and ANFIS. The number of pole pairs in a mechanical motor with a speed of 2000 rpm is 3, and 12th harmonics frequency is 1.2 kHz.…”

“…Table 5 shows the comparison of torque ripple. Table 5 shows that the proposed ANFIS achieves less torque ripple of 0.53 Nm which is much better than the existing SVPWM-DTC [22]. The introduction of flux linkage oscillations is achieved through voltage harmonics.…”

“…To improve the dynamics of torque and flux, a hybrid control technique [21] for PMSM was established, but the switching loss was high. The Space Vector Pulse Width Modulation based DTC (SVPWM-DTC) [22] was suggested for PMSM; due to the bandwidth constraint, it causes a huge torque ripple in the motor. A novel Dual Cost Function Model Predictive Direct Speed Control (DCFMPDSC) [23] was presented with duty ratio optimization for PMSM drives.…”
