Dynamic Voltage Vector Control and Hybrid SVPWM Modulation for Current Ripple Suppression in OW-PMSM System

Year: 2026

Type: article

Abstract: The dual-inverter open-winding permanent magnet synchronous motor drive system offers significant advantages in steady-state planning and transient control of the motor. However, conventional modulation and control methods suffer from large torque ripple, high inverter switching losses, and limited stability. This paper proposes a reference-value-judged voltage allocation algorithm that coordinates d-axis current and electromagnetic torque tracking while respecting the maximum voltage amplitude limit. A hybrid SVPWM modulation strategy is also introduced, which combines the centered-zero-vector type and the end-placed-zero-vector type using an optimized switching strategy. Finally, a comparative simulation is conducted with a control group to verify that the proposed algorithm strictly ensures speed and torque tracking performance, reduces torque ripple and inverter switching frequency, improves system stability, and reduces inverter switching losses. The proposed methods effectively mitigate torque ripple and switching losses while maintaining precise tracking, offering a promising solution for high-performance dual-inverter drives.
