Unmanned aerial vehicle (uav) merupakan wahana udara tanpa awak yang dikendalikan dari jarak jauh. Pemanfaatan ini salah satunya sebagai media pemantauan memiliki keunggulan pada nilai efektifitas kerjanya. Untuk melakukan pengamatan daerah perkotaan diperlukan rancangan pesawat uav dapat lepas landas dan mendarat secara vertikal (vtol) kecepatan tinggi dalam perpindahan satu tempat ke lainnya....

This paper explores a novel single tail tilt servomotor tri-rotor ducted vertical takeoff and landing unmanned aerial vehicle system (VTOL-UAV), proposes compound control method combining disturbance observer, model predictive (MPC) sliding mode nonlinear dynamic inversion (NDI), realizes the robust tracking of VTOL-UAV trajectory under disturbance. Specifically, inner loop adopts inverse which...

A Vertical Take-Off and Landing-Plane (VTOL-Plane) is an Unmanned Aerial Vehicle (UAV) that combines multirotor fixed-wing configurations. It has a good cruise range compared to VTOL vehicle. Furthermore, it can take-off land vertically. This technology ideal for surveillance/monitoring missions transmitting data in real-time. study discusses the design of VTOL-Plane with preset Design Requirem...

This paper presents two image-based controllers designed to track a target moving at constant velocity. Dynamical model of VTOL type UAV is manipulated to facilitate the control design. The first controller is designed for known target velocity while the second controller is designed for unknown target velocity. The work is motivated by the technique of spherical-projection used to control 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...

In this paper we address the development of a single-rotor tail-sitter Unmanned Aerial Vehicle (UAV), whose configuration provides structural benefits for flight stabilization. The mathematical model of the vertical take-off landing (VTOL) aircraft is obtained through the Newton-Euler approach. In order to stabilize the vehicle we employ a control algorithm based on separated saturation functio...

The optimisation of a tail-sitter UAV (Unmanned Aerial Vehicle) that uses a stall-tumble manoeuvre to transition from vertical to horizontal flight and a pull-up manoeuvre to regain the vertical is investigated. The tandem wing vehicle is controlled in the hover and vertical flight phases by prop-wash over wing mounted control surfaces. It represents an innovative and potentially simple solutio...
