Torque Ripple Suppression Control for PM Motor With High Bandwidth Torque Meter
2009 IEEE Energy Conversion Congress and Exposition, 2009PM motor drive systems are widely used in many industrial applications. However, PM motors have the fluctuation of the magnetic field distribution which produces the torque ripple. Dead time of the inverter, offset of sensors and current measurement errors lead to the torque ripple, too.

Research on Torque Ripple Suppression of the Slotted Limited Angle Torque Motor
IEEE Transactions on Magnetics, 2021This article presents the theoretical analysis and numerical modeling of various cogging torque suppression methods of the slotted limited angle torque motor (LATM). The relationship between the cogging torque, the output characteristics, and the structure parameters of new methods is revealed by derived equations and finite-element analysis (FEA ...

Anticogging: Torque ripple suppression, modeling, and parameter selection
The International Journal of Robotics Research, 2015Smooth motion is critical to some robotic applications such as haptics or those requiring high precision force control. These systems are often direct-drive, so any torque ripple in the motor output must be minimal. Unfortunately, low-torque ripple motors are expensive.

Torque ripple suppression control for permanent magnet motors
2014 European Control Conference (ECC), 2014Permanent magnet motors are largely employed due to their high performances in terms of efficiency, power factor and power density. However, non-uniformity into the generated torque may heavily limit their use. In this paper a novel approach is proposed to cancel torque ripple when motor parameters are unknown.

Suppressing Pulsating Torques: Torque Ripple Control for Synchronous Motors
IEEE Industry Applications Magazine, 2014This article proposes a novel control technique for suppressing pulsating torques in permanent magnet synchronous motors (PMSMs) and synchronous reluctance motors (Syn-RMs). This torque-control system is based on instantaneous torque estimation with a rigorous analytical model that can account for spatial harmonics.

A control strategy to suppress torque ripple of brushless DC motor
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The paper proposes an advanced communication control strategy aiming at the problem of torque ripple during the commutation process of Brushless DC motor (BLDCM). By commutating in advance, the slope of off-phase current and conduction-phase current are adjusted.

Magnetization Process of an HTS Motor and the Torque Ripple Suppression
IEEE Transactions on Applied Superconductivity, 2009This paper describes in detail the magnetization process of a synchronous motor, constructed with High Temperature Superconducting (HTS) elements on the rotor. The Pulse Field Magnetization (PFM) method is considered to magnetize the HTS rotor as a four-pole trapped flux magnet. A 2D model is built for the magnetization process.

Torque Ripple Suppression of Switched Reluctance Motor Based on Torque Sharing Strategy
Advanced Materials Research, 2014The torque ripple is the main disadvantage of switched reluctance motor (SRM). In order to reduce the torque ripple of SRM, and improve the performance of the system, the torque sharing strategy was combined with RBF neural network for the purpose of torque ripple suppression by controlling the winding current of each phase.
