Analysis and Suppression of Torque Ripple for Doubly Salient Electro-Magnetic Motor

2009 IEEE Industry Applications Society Annual Meeting, 2009
The Doubly Salient Electro-magnetic Motor (DSEM) is subject to significant torque ripple when working with traditional standard angle control method. To weaken the effects of the torque ripple for further applications of DSEM such as wind power generation and aerospace, in-depth analysis of the ripple generation mechanism and two novel strategies of ...

Quick torque ripple suppression controlled fast position servo based on hybrid system of disturbance observer and torque ripple table

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
In the field of high-precision position control, the position response requires that there is no vibration. However, a permanent magnet synchronous motor (PMSM) has a wide variety of torque-ripple components, including cogging torque and flux harmonics, which degrade the control performance.

Current harmonic selection for torque ripple suppression based on analytical torque model of PMSMs

Journal of Power Electronics, 2020
For permanent magnet synchronous motors (PMSMs) without sufficient design optimization, it is necessary to inject current harmonics to suppress torque ripple. Due to the influence of magnetic saturation, the current harmonics for torque ripple suppression changes with the electrical loads.

Study on suppressing unreasonable torque ripple in SPMSM-DTC system

2017 36th Chinese Control Conference (CCC), 2017
In order to suppress unreasonable torque ripple of direct torque control (DTC) in surface permanent magnet synchronous motor (SPMSM), the SPMSM-DTC mode is established and the effect of voltage vectors selected by switching table on torque is analyzed. The conclusion of the change in torque is contrary to expectation when the changes of stator flux and

Noise reduction by torque ripple suppression in brushless DC motor

PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002
The acoustic noise of a brushless DC motor is thought to be partly due to torque ripple. This paper examines, both analytically and experimentally, the effect of ripple reduction on the noise reduction. To realize the torque ripple reduction an overlapping of phase current is utilized here.
