Visual servo control using homography estimation for the stabilization of an X4-flyer

In this paper we study image based visual servo (IBVS) control of a four rotor vertical take-off and landing (VTOL) craft known as an X4-flyer. The approach taken is tailored to planar visual targets and is based on a reformulation and extension of 2 1/2 D image-based visual servo design to the control of dynamic under-actuated systems. Exponential stability of the closed loop system is proved and simulation results are presented.
