Current Delta Control For Conical Bearingless Switched Reluctance Motors
PROCEEDINGS OF THE 2018 13TH IEEE CONFERENCE ON INDUSTRIAL ELECTRONICS AND APPLICATIONS (ICIEA 2018)(2018)
Abstract
The rotor of the conical bearingless switched reluctance motor can be fully levitated and rotate at the same time without magnetic bearings. This paper proposes a novel control method for this type of motors. By re-constructing the winding currents as three different components, the five-axes positions and rotor angular velocity can be regulated by the axial-force current, the radial-force currents and the torque current respectively. The theoretical analyses and simulation results both verify the demonstrated performance of the proposed method.
