Sigmoid-Based Adaptive-Bandwidth ESO for Robust Attitude Control of Ducted Fan UAVs Under Near-Ground Disturbances
To addressthe challenge of attitude control in quad-ducted fan unmanned aerial vehicles (UAVs) under coupled disturbances comprising thrust lag, ground effect and a composite wind field during near-ground flight and to mitigate the inherent trade-off between disturbance rejection and noise suppression in fixed-bandwidt...
