Velocity and imbalance observer control circuit for active magnetic bearing or damper

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