Development of a VTOL mini UAV for multi-tasking missions

An Augmented Reality System for Multi-UAV Missions

Augmented Reality (AR) is a relatively new field of research with diverse application areas. In this paper we present a novel approach in using AR technology in multiple Unmanned Air Vehicle (UAV) missions to augment the UAVs’ sensor systems with Decentralised Data Fusion (DDF) capable sensors, performing multi-modal sensor registration and cooperative control experiments. The AR system is bein...

Nonlinear attitude and gyroscope's bias estimation for a VTOL UAV

This paper addresses the problem of attitude and heading restitution for a VTOL UAV. We describe an observation strategy to restitute the complete attitude matrix of the vehicle starting from Inertial Measurement Unit (IMU) and magnetometers. This study is a part of the development of the ducted fan UAV designed by Bertin Technologies. First, a measured orientation matrix is calculated from bot...

Hybrid Propulsion System Design of a VTOL Tailsitter UAV

Tailsitter UAVs with their combined vertical take off and landing (VTOL) and fixed-wing aircraft with full flightspeed regime capability provides a distinct alternative to rotary-wing and ducted fan UAVs (OAVs). ITU-BYU Tailsitter concept aims to obtain the energy efficient regimes across the VTOL and the cruising flight regimes. This paper describes the hybrid propulsion system design approach...

Control of a VTOL UAV via Online Parameter Estimation

Due to their ability to hover and to fly “low and slow” VTOL UAVs are of extreme strategic importance. The task of control of VTOL UAVs is however complicated as they exhibit highly coupled nonlinear dynamics and inherent instability. These intricacies limit the performance of linear control techniques since a single linearized state space model represents only a limited part of the flight enve...
