DUAL-FREQUENCY ACTIVE VIBRATION CONTROL

摘要

A system for active vibration control includes an actuator configured to reduce the impact of a vibratory load imposed on an airframe of a rotorcraft to an amount that is less than a threshold; and a controller configured to determine the vibratory load based on the data, and set an eccentric rotational speed of an actuator at a first frequency and modulate the eccentric rotational speed by a second frequency based on the vibratory load. Also a method includes obtaining, by the controller, data; determining, by the controller, a vibratory load based on the data; and setting, by the controller, an eccentric rotational speed of an actuator at a first frequency and modulating the eccentric rotational speed by a second frequency based on the vibratory load.
