Data-Driven Modeling of Ground Effect For UAV Landing on a Vertical Oscillating Platform

IEEE/RJS International Conference on Intelligent RObots and Systems
Landing on a vertically oscillating platform poses a significant challenge for multi-rotor unmanned aerial vehicle (UAVs) due to the time-varying ground effect (GE). In this work, we formulated a data-driven GE dynamic model that accurately describes the
