ACTIVE VIBRATION CONTROL DEVICES, SYSTEMS, AND METHODS

摘要

Improved active vibration control (AVC) devices (20), systems, and related methods are provided herein. An AVC device (20) includes a controller (24) adapted to receive real-time aircraft information and adjust at least one control parameter as a function of the real-time aircraft information is provided. An AVC device is adapted to detect changes in real-time aircraft information, as the aircraft moves from a steady state to transient performance, low and high air speeds, or vice versa. An AVC system (e.g., AVCS) includes one or more sensors (22), one or more actuators (26), and a controller (24) adapted to receive real-time aircraft information and adjust at least one control parameter. In some aspects, a method of controlling vibration within an aircraft includes receiving vibration information from at least one sensor (22), receiving real-time aircraft information from an avionics system (40), adjusting at least one control parameter used in a control algorithm, and generating a force command.

1. An active vibration control system (AVCS) for use in aircraft, the AVCS comprising:
a controller adapted to receive real-time aircraft information and adjust at least one control parameter in the AVCS as a function of the real-time aircraft information, wherein the real-time aircraft information is selected from the group consisting of forward air speed, rotor speed, pitch, yaw, roll, altitude, relative altitude, aircraft weight, weight on wheels, aircraft center of gravity, glass cockpit mode and combinations thereof; at least one sensor; and at least one actuator.
