Agressive flight control techniques for a fixed wing unmanned aerial vehicle
(Stellenbosch : University of Stellenbosch, 2009-03)
This thesis investigates aggressive all-attitude flight control systems. These are flight controllers
capable of controlling an aircraft at any attitude and will enable the autonomous
execution of manoeuvres such as high ...
Full state control of a Fury X-Cell unmanned helicopter
(Stellenbosch : University of Stellenbosch, 2009-03)
This thesis describes the successful development of an autopilot for an unmanned
radio controlled helicopter. It presents a non-linear helicopter model. An adaptive
linearised model is derived and used to design a ...
A comparison of control systems for the flight transition of VTOL unmanned aerial vehicles
(Stellenbosch : University of Stellenbosch, 2008-03)
This thesis details the development of linear control systems that allow a
vertical take-off and landing unmanned aerial vehicle to perform transitions
between vertical and horizontal flight. Two mathematical models are ...
HV Transmission line and tower inspection safe-fly zone modelling and metrology
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: The deployment of Unmanned Aerial Vehicles (UAV) for power line inspection
requires the definition of safe-fly zones. Transient Over-Voltages (TOVs) on the
Overhead Transmission Lines (OHTLs) put the ...
Kinodynamic planning for a fixed-wing aircraft in dynamic, cluttered environments : a local planning method using implicitly-defined motion primitives
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: In order to navigate dynamic, cluttered environments safely, fully autonomous Unmanned
Aerial Vehicles (UAVs) are required to plan conflict-free trajectories between two states
in position-time space ...
Online system identification for fault tolerant control of unmanned aerial vehicles
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: In this thesis the strategy for performing System Identification on an aircraft is presented. The
ultimate aim of this document is to outline the steps required for successful aircraft parameter
estimation ...
Investigation of an aeroelastic model for a generic wing structure
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Computational Aeroelasticity is a complex research field which combines structural
and aerodynamic analyses to describe a vehicle in flight. This thesis investigates the
feasibility of including such ...
Motion planning algorithms for autonomous navigation for a rotary-wing UAV
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: This project concerns motion planning for a rotary wing UAV, where vehicle controllers are
already in place, and map data is readily available to a collision detection module. In broad
terms, the goal ...
Autonomous landing of a fixed-wing unmanned aerial vehicle using differential GPS
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: This dissertation presents the design and practical demonstration of a flight control system (FCS) that is capable of autonomously landing a fixed-wing, unmanned aerial vehicle (UAV) on a stationary ...
Monocular vision assisted autonomous landing of a helicopter on a moving deck
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: The landing phase of any helicopter is the most critical part of the whole flight envelope,
particularly on a moving flight deck. The flight deck is usually located at the stern of the ship,
translating ...
