    Abstract

    This paper presents a nonlinear controller for hovering flight and touchdown control for a Vertical Take-off and Landing (VTOL) Unmanned Aerial Vehicle (UAV) using inertial optical flow. The VTOL vehicle is assumed to be a rigid body, equipped with a minimum sensor suite (camera and IMU), manoeuvring over a textured flat target plane. Two different tasks are considered in this paper: the first concerns the stability of hovering flight and the second one concerns regulation of automatic landing using the divergent optical flow as feedback information. Experimental results on a quadrotor UAV demonstrate the performance of the proposed control strategy.
