Abstract
A method of operating a vibration control system (VCS) using a single actuator which operates to attenuate a system frequency of a system is provided. The method includes determining whether current vibrations at a non-system frequency exceed a predefined level, determining a system response to compensate for the current vibrations exceeding the predefined level and adjusting the force response of the single actuator to respond to a system frequency and the non-system frequency according to the determined system response toward compensating for the current vibrations.

A method of operating a vibration control system (VCS) using a single actuator which operates to attenuate a system frequency of a system, the method comprising:
- determining whether current vibrations at a non-system frequency exceed a predefined level;
- determining a system response to compensate for the current vibrations exceeding the predefined level;
- and
- adjusting the force response of the single actuator to respond to a system frequency and the non-system frequency according to the determined system response toward compensating for the current vibrations.
A vibration control system (VCS) to attenuate vibrations on a frame, the VCS comprising:
- an actuator to compensate for system and non-system frequency vibrations of the frame;
- and
- a flight computer disposed to sense current vibrations and to control operations of the actuator to operate a first frequency to attenuate the system frequency vibrations, to detect whether the current vibrations are at a non-system frequency which exceeds a predefined level, to determine a system response to compensate for the non-system frequency vibrations exceeding the predefined level and to control the actuator to additionally provide a second frequency to attenuate the non-system frequency vibrations to compensate for the system and non-system current vibrations.
