Robust sensorless load angle control for stepping motors [PDF]

open access: yes, 2015
In industry, the bulk of the stepping motors is driven in open loop full-step mode with maximum current to avoid step loss. This results in noisy operation due to torque ripples and a poor energy-efficiency.

Sensorless control for surface mounted PM machine with a high inertial load

open access: yesCES Transactions on Electrical Machines and Systems, 2018
PM machine or Permanent magnet synchronous motor (PMSM) is a nonlinear system with multivariable couplings. To achieve the sensorless control of a PMSM with high inertial load, a modified current observer, using PI regulator instead of sliding mode ...

Stator resistance identification of PMSM

open access: yesIFAC-PapersOnLine, 2016
Abstract: The following paper describes an online identification of a stator resistance of a permanent magnet synchronous motor. The resistance is identified by two methods. The first one is a frequency analysis based on an injection of a harmonic signal to the control. This method utilizes knowledge of synchronous motor schema in d-q coordinates and

Signal injection and averaging for position estimation of Permanent-Magnet Synchronous Motors

open access: yes, 2012
Sensorless control of Permanent-Magnet Synchronous Motors at low velocity remains a challenging task. A now well-established method consists in injecting a high-frequency signal and use the rotor saliency, both geometric and magnetic-saturation induced ...
