ABSTRACT:
A system for minimizing periodically induced vibration in a mechanical structure, particularly rotary shaft apparatus that is not limited to the use of any particular number or type of forcers or sensors and requires no knowledge of the mechanical structure's transfer function. In accordance with a preferred embodiment the system senses periodically induced vibration utilizing a plurality of sensors and produces a complex output representative of the algebraic sum of the vibrations sensed for each harmonic and counteracting the vibration with a plurality of actuators operatively coupled to the structure by producing a counteracting vibration therein in response to a complex input signal for each actuator in the form of a matrix of system responses to vibrational inputs at selected harmonics of interest. More specifically, the complex inputs for the actuators are produced on the basis of an adaptation cycle wherein the effect of an adjustment of the complex inputs on the complex outputs is utilized to determine the nature of a successive adjustment of the complex inputs utilizing a control algorithm.
