X-plane uçuş simulasyonundan elde edilen uçuş datası kullanılarak sabit kanatlı bir hava aracının sistem modeli belirlenmesi ve kontrolü.

In this thesis, a linear state-space model of an aircraft is obtained by applying numerical integration system identification method. Flight test data used in the system identification is obtained by using X-Plane flight simulation program. In X-Plane Flight Simulator, the flight tests are made by using different excitations on the control surfaces. The linear models obtained by system identification are verified by applying the inputs to the linear model and then the outputs are compared with the X-Plane flight data. The identified linear models are used to design autopilots. Stability augmentation systems have been designed to alter dynamic character of the aircraft by using pole placement method. First the aircraft is made easier to fly by adding damping to its modes. Then damping is reduced to mimic dynamic behavior of an aircraft with poor handling qualities. Both system identification and feedback control studies are performed in Matlab/Simulink environment and connection with X-Plane is established via UDP (User Datagram Protocol)M.S. - Master of Scienc
