Disturbance Observer Based Hovering Control of Quadrotor Tail-Sitter VTOL UAVs Using H∞ Synthesis.
IEEE Robotics and Automation Letters(2018)
摘要
Hybrid VTOL UAVs such as tail-sitters allow several key maneuvers such as vertical takeoff, landing, and hovering while at the same time maintaining superior aerodynamic efficiency at level flight. However, the large wing area of a tail-sitter at hovering makes it rather sensitive to the cross wind. In this letter, we present a disturbance observer (DOB) based control method to improve its hoverin...
