Biodynamic Feedthrough: Current Status and Open Issues

On Task Dependence of Helicopter Pilot Biodynamic Feedthrough and Neuromuscular Admittance: An Experimental and Numerical Study

“…The estimation of the dependence of the BDFT from the type of task required workload is still an open area of research [13], especially in relation with helicopter piloting. Research effort in the modeling aspects of the relationship between task, workload and BDFT should follow suit, with the goals of developing design tools that will enhance robustness of novel rotorcraft with respect to RPC/PAO phenomena, analysis tools capable of identifying possible critical issues in current designs, and to exploit a higher-level insight made available from physics-based models into pilot training.…”

Admittance-Adaptive Model-Based Approach to Mitigate Biodynamic Feedthrough

“…This switching strategy is still far from a truly adaptive approach, where the model parameters would be adapted in real-time, based on a continuous measurement of the neuromuscular dynamics. Currently, the techniques required to accurately and robustly obtain these measurements are under development [31], [32]. Hence, as a proof-of-concept, the approach is implemented in this elementary fashion.…”

“…This issue can only be properly addressed with online identification techniques that allow for real-time adaptation of the cancellation model to the current settings of the NMS. These methods are currently under development [31], [32]. Issues regarding the implementation and certification of such BDFT cancellation systems, e.g., aerospace vehicles, are to be addressed in future research.…”
