摘要

An active vibration damping system (110) comprising: a plurality of actuators (150-155) corresponding to and adjacent to each engine (102) of an aircraft (100) , And is configured to detect one or more magnitudes and frequencies of vibration and noise generated by the respective engines and to generate one or more feedback signals of vibration and noise At least one sensor (650) connected to each of the plurality of actuators and to the at least one sensor, respectively, and controlling up to two of the plurality of actuators for each engine based on the feedback signal And to control one or more of the vibration and noise of each engine due to the rotation of the respective engine.BACKGROUND OF THE INVENTION 1. Field of the Invention
