1. A vibration suppressor system comprising:
- an actuator system for applying a force to a structure;
a power supply operable to power said actuator system; and
a control system operable to control power from said power supply to said actuator system using a power algorithm configured to suppress a vibration of said structure independently from a vibratory feedback of the structure and based on a function that has a single control objective and that receives real electric power of said actuator system as input,wherein said power algorithm is configured to regulate an actuator voltage that is supplied to said actuator system from the power supply based on a phase angle difference between an actuator current and said actuator voltage,wherein said single control objective comprises a regulation of said actuator current to lead or lag said actuator voltage by the phase angle difference,wherein said power algorithm is further configured to cause said actuator current to lead or lag said actuator voltage by the phase angle difference.

Abstract
A vibration suppressor system includes a control system operable to control power from a power system to an actuator system in response to a minimal actuation power algorithm. The minimal actuation power algorithm employs a real electric power consumption of the actuator system as a single control objective function to suppress a vibration of the structure.

9. A method of vibration suppression comprising:
-
controlling power to an actuator system for applying a force to a structure by using a power algorithm that suppresses a vibration of said structure independently from a vibratory feedback of the structure and suppresses the vibration based on function that has a single control objective and that receives real electric power of said actuator system as input, wherein the power algorithm regulates an actuator voltage that is supplied to the actuator system from the power supply based on a phase angle difference between an actuator current and the actuator voltage, wherein the single control objective comprises a regulation of the actuator current to lead or lag the actuator voltage by the phase angle difference, wherein the power algorithm causes the actuator current to lead or lag the actuator voltage by the phase angle difference. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
