  • Model-following control system using acceleration feedback
    Patent number: 6189836
    Abstract: A feedback system for reducing the effects of destabilizing forces in a vehicle (e.g. helicopter) by utilizing acceleration feedback data sensed by an acceleration sensor located in the vehicle. This sensed acceleration signal is passed through a low-pass filter and combined with a command signal to produce an error signal. The error signal is multiplied by a predetermined gain to produce a corrective signal that is utilized by actuators to adjust an adjustable surface, such as a swashplate, on the vehicle.
