ABSTRACT:
"Velocity Observer" and "Imbalance Observer" circuits are used to control the journals in the magnetic field of an attractive type active magnetic bearing and/or damper. The circuits are characterized by the use of integrators rather than differential components. The velocity observer circuit uses a position feedback loop and a velocity observer feedback loop, both with variable gain, to control the levitation of the journal in the magnetic field. The imbalance observer circuit recreates the journal acceleration directly from the displacement measurement and can be used optionally on-line and off-line to suppress vibrations.
