Quadcopter Fast Pure Descent Maneuver Avoiding Vortex Ring State Using Yaw-Rate Control Scheme
RA-L 2021
Due to their simplicity and agility, nowadays drones especially quadcopters have become popular in many applications. However, they still have a velocity limitation on fast descent maneuvers, which is known as Vortex Ring State (VRS) constraint in the literature. In this paper, first, we provide a b
