This study surveys the developments in satellite attitude determination and control system,
especially for microsats. This survey is not intended to be complete but is limited to the most …

The last decades have witnessed a rapid increase of Earth observation satellites (EOSs),
leading to the increasing complexity of EOSs scheduling. On account of the widespread …

The permanent magnet bearing (PMB) has the advantage of non-contact support, which is
used to reduce mechanical friction and wear of journal bearings. The effect of translation or …

Here, a novel flywheel structure is proposed with passive permanent magnet (PM) bearings
in the radial and axial directions and an active magnetic bearing (AMB) in the axial direction …

Purpose In order to improve the levitation performance and robustness of the active
magnetic bearings with slice rotor, an adaptive backstepping control method is studied …

Some sources of disturbance inevitably exist in magnetic bearings systems in the process of
operation. This article proposes a disturbance suppression scheme for active magnetic …

A SMPMSM drive system is a typical nonlinear system with time-varying parameters and
unmodeled dynamics. The speed outer loop and current inner loop control structures are …

The nonlinear dynamics are studied for an active magnetic bearing (AMB) system under the
low-frequency sinusoidal excitation, which can affect the operational stability of a high …

Featured Application Active magnetic bearings are very useful in devices requiring high
speed or noncontact condition, such as high-speed air compressors, flywheel energy …

Friction and vibrations hindering high-speed are the most pertinent problems facing the
rotating machines. Thus, friction and vibration attenuation are essential in improving the …
