摘要

Double-winding Permanent Magnet Synchronous Motor (DW-PMSM) is widely utilized in aerospace, marine, and other industries due to its numerous advantages such as enhanced reliability, high power density, and reduced torque ripple. Realizing the position no sensor control of the DW-PMSM can improve the performance of the system. This paper presents a novel approach called the pulsating high-frequency square wave injection method for rotor position estimation in a DW-PMSM. Additionally, a technique is proposed to mitigate torque ripple, resulting in smoother operation of the motor. A comparison is made between position no sensor control systems of γ = 0°and γ = 30° DW-PMSMs utilizing high-frequency square wave injection. The simulation results are evaluated and compared to confirm the viability of the proposed method.
