GES: Ground Effect Stabilizer — Onboard-Sensor-Based Feedforward Estimation of Ground Effect on Irregular Terrain via Machine Learning versus Analytical Models

This paper demonstrates that while machine learning models can accurately predict ground effect on irregular terrain offline, their deployment in closed-loop control often fails to improve performance over analytical baselines due to unaccounted actuator-level dynamics and asymmetric sensitivity to overprediction biases, necessitating specific correction strategies like asymmetric clamping rather than relying solely on predictive accuracy.
