![]() It behaves like a helicopter but with higher speeds in forward flight. The vehicle is a Vertical Take-Off Landing (VTOL) type with two symmetric rotors on the wings, one aft rotor on the aft body. In the thesis, automatic flight control system is designed for Tilt Duct Unmanned Aerial Vehicle (UAV). Ünlü, Tuğba Tekinalp, Ozan Department of Aerospace Engineering (2009) It is also demonstrated that, with redundant control surfaces it is possible to recover the aircraft during a maneuver even some of the control surfaces are damaged or got stuck at a particular deflection.įlight control of a tilt duct uav with emphasis on the over actuated transition flight phase Although both of the static control allocation methods are found to be quite successful to realize the maneuvers, the new blended inverse algorithm is shown to be more effective in controlling the aircraft when some of the control surfaces are lost. It is shown that with redundant control surfaces, fault tolerant control is possible. ![]() For this purpose, an aircraft with three sets of ailerons is employed. Two static control allocation methods are examined: Moore-Penrose pseudo inverse and blended inverse. The flight control system is designed using classical control techniques. The fault tolerant control of an over actuated UAV is the main concern of the thesis. Performances of the designs for full autonomous flight are tested through nonlinear simulations for different maneuvers in the presence of uncertainties and disturbances in the aircraft model. ![]() Automatic flight control system of the conventional UAV is designed by using both classical and robust control methods. A nonlinear simulation model including the flight mechanics equations together with the interpolated nonlinear aerodynamics, environmental effects, mass-inertia properties, thrust calculations and actuator dynamics is created trim and linearization codes are developed. This thesis describes the automatic flight control systems designed for a conventional and an over actuated unmanned air vehicle (UAV). ![]()
