Mitigation of Biodynamic Feedthrough for Touchscreens on the Flight Deck

A review of biodynamic feedthrough mitigation techniques

Biodynamic feedthrough (BDFT) refers to a phenomenon where accelerations cause involuntary limb motions which, when coupled to a control device, can result in unintentional control inputs. Biodynamic feedthrough can occur in many different vehicles and under various conditions, which makes it highly relevant to study its mechanisms. In this paper the possible biodynamic feedthrough mitigation t...

Robust Controller Design for Cancelling Biodynamic Feedthrough

There are many manual control tasks in which the operator base moves in response to joystick movement. Base motion feedback can interfere with the joystick and operator dynamics, resulting in instability and reduced performance. This paper proposes a novel approach to the cancellation of such “biodynamic feedthrough”. A model-based approach is used to formulate a μ-synthesis robust performance ...

A Practical Biodynamic Feedthrough Model for Helicopters

Biodynamic feedthrough (BDFT) occurs when vehicle vibrations and accelerations feed through the pilot’s body and cause involuntary motion of limbs, resulting in involuntary control inputs. BDFT can severely reduce ride comfort, control accuracy and, above all, safety during the operation of rotorcraft. Furthermore, BDFT can cause and sustain Rotorcraft-Pilot Couplings (RPCs). Despite many studi...
