Continuous Time Estimation of Pilot Biodynamic Response for Vertical Bounce Coupling Assessment

This work addresses the estimation of time-varying pilot parameters within Rotorcraft– Pilot Couplings. An analytical, physics-based model with the minimum number of degrees of freedom represents the coupled pilot–helicopter dynamics. Parameter tracking uses sigma-points filtering to capture time-varying parameter characterization. Simulations under diverse conditions accurately reconstruct the trajectories of states and parameters in real time. The approach provides a practical basis for robust online identification and control strategies to mitigate Pilot-Assisted Oscillations.
