1. A rotating machinery assembly, said assembly comprising:

  • at least one movable rotor member which is deployed upon said rotating machinery assembly, said at least one movable rotor member having a weight distribution, wherein said at least one movable rotor member is selectively movable to produce a corrective phasor with a correction magnitude and a correction phase angle;

    a vibration sensor which senses a vibration and generates a vibration signal; and

    a controller for controlling said at least one movable member wherein said controller includes a microprocessor operating with stored control programs, said controller receives said vibration signal from said vibration sensor and said control programs calculate a phasor value to selectively move said at least one movable rotor member to produce a corrective phasor to reduce said sensor vibration.
