    Designing autopilot system for fixed-wing flight mode of a tilt-rotor UAV in a virtual environment: X-Plane
    (2018) Yalçın, Mehmet Kürşat; Ersoy, Erhan
    This paper describes an autopilot system design to regulate the altitude, heading and forward speed inthe fixed-wing flight mode of the Osprey V22 VTOL (vertical takeoff and land) tilt rotor UAVaccordingly to a reference, which is generated the trajectory sub-block. X- Plane flight simulatordeveloped by Laminar Research, is used to test and optimize the parameter values of the autopilotsystem, which is designed using feedback, feedforward and PID controllers in MATLAB / Simulinkenvironment (Software in the Loop- SIL). The receiver and sender blocks to perform the datainteractions between MATLAB / Simulink and X-Plane flight simulator are created in MATLAB /Simulink environment. The receiver block is used to transfer data from the X-Plane flight simulator tothe controller, while the sender block is used to transfer control signals from the controller to the XPlane flight simulator program. The data communication between the two is UDP. The autopilotsystem under test is embedded in the Raspberry-Pi minicomputer and a hardware-in loop (HIL) testsystem created. The reaction of the control algorithm running on the Raspberry-Pi minicomputer tothe virtual sensor data generated by the X-Plane flight simulator investigated. It is observed that, theOsprey-V22 aircraft can perform tasks autonomously in the horizontal flight mode, from theexperiments and the results obtained. This study also describes the first stage of an undergoing projectwhich aims to develop a robust autopilot for Osprey V22 VTOL UAV.

    Matlab/Simulink ve X-Plane Uçuş Benzetim Programi Arasi UDP Haberleşme ile Veri Transferi
    (Institute of Electrical and Electronics Engineers Inc., 2019) Ersoy, Erhan; Yalcin, Mehmet Kursat
    Drone or other Unmanned Aerial Vehicles (UAVs), known as four-rotor, are actively used by different industries, besides using for hobby purposes. Traffic control, advertising and cargo transportation can be given as an examples of areas where UAVs are used. The success of the UAVs in the specified sectors depends on the success of the autopilot systems. The slightest error that may occur in autopilot systems used in UAVs causes material damage and even makes them unusable. The best way to test the success of autopilot systems is flight tests. The fact that flight tests are costly necessitates the use of loop systems in software and hardware that will enable these tests to be performed with the use of computers and various hardware in the laboratory environment. Because of this reason, in this study, data transfer by UDP communication between control system at Matlab / Simulink enviroment and X-Plane flight simulation program developed by Laminar Research company which presents the most realistic flight dynamics and environmental conditions explained. © 2019 IEEE.
