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.

Abstract
A balance assembly for a rotating assembly comprising: a first movable rotor and a second movable rotor which are selectively movable about the rotating assembly; and a controller with a microprocessor operating with stored control programs for controlling movement of the first movable rotor and second movable rotor and adapted to calculate a value and to periodically modify the value and to cause the first movable rotor and the second movable rotor to move in accordance with the calculated value and the modified value, wherein the values are adjusted during a plurality of control iterations to reduce vibrational signals from an at least one vibration sensor.
