Traditional constant current sum (CCS) distribution strategy is always employed in the
nonlinear active magnetic bearing (AMB) system control for linearization, but the bias current …

A radial clearance adjustable bearing is proposed in this study. The structure and working
principles of the adjustable bearing are introduced. This adjustable bearing can change the …

This research aims to test the limits of control effectiveness for an active magnetic bearing
(AMB) system subjected to external acceleration disturbances. An adaptive output …

Active magnetic bearings (AMBs) have unique superiority in vibration reduction and
nowadays have been widely used in permanent magnet synchronous motor (PMSM). To …

Permanent-magnet (PM) biased magnetic bearings use a magnet to produce the bias field
rather than applying a bias current, thereby eliminating the associated electrical power …

Many structural systems, such as wind turbines, are exposed to high levels of stress during
operation. This is mainly because of the flow-induced vibrations caused by the wind load …

Adjustable/controllable bearings are the future direction of journal bearings and are used to
correct design blind spots and handle changing operating conditions. This study …

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 …

For the vibration suppression for a slice rotor supported by active magnetic bearings (AMBs),
a backstepping controller based on fractional-order adaptive update laws is proposed. The …

In the complex environment of the battlefield and dust weather, hard objects including birds,
bullets, sand and others will inevitably cause impact damage to the compressor blades of …
