Abstract

This paper analyzes and compares the typical rotating high-frequency voltage injection (RTHF) method and the typical pulsating high-frequency voltage injection (PSHF) method in terms of torque ripple and vibration. Analysis and experiment results indicate that the PSHF performs better when it comes to torque pulsation and vibration. In addition, it is more suitable for rim motors which have strict restrictions on vibration. However, the estimated rotor position in PSHF has multiple convergence points. In addition, the filters used in PSHF can degrade the dynamic response of the PMSM sensorless field oriented control (SLFOC) system. An improved PSHF method compensated by Hall signals is proposed to accelerate the estimation process and improve the system stability in the presence of sudden load disturbances. The improved method is verified on an 11 kW rim motor experimental platform.
