In this thesis, a mathematical model of a small unmanned aircraft is implemented where the static and dynamic stability derivative coefficients are found by Digital DATCOM software. Several control methods are applied such as PID control, LQT, SMC. Two types of Sliding mode controllers are designed using different sliding surfaces. Linearized aircraft models which are trimmed at two different airspeeds are used to design controllers. A guidance block is implemented to guide aircraft with waypoints. Different guidance methods are used to suppress wind disturbance effects. Model Predictive Control is implemented to track the desired tracks. These desired tracks are generated by steepest decent algorithm. The tracking performances of mentioned controllers are tested in MATLAB/Simulink environment.

System identification and control of a fixed wing aircraft by using flight data obtained from x-plane flight simulator Çetin, Ender; Kutay, Ali Türker; Department of Aerospace Engineering (2018) 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 f...
Nonlinear guidance and control of leader-follower UAV formations Kumbasar, Sarper; Tekinalp, Ozan; Department of Aerospace Engineering (2015) In this thesis work, two nonlinear guidance methods are proposed to control the autonomous formation flight: State Dependent Riccati Equation method and Lyapunov function method. Leader-Follower formation scheme is chosen and a pair of fighter aircrafts are used in simulations. One of them is chosen as the leader and it carries out the commanded maneuvers. Other aircraft is the follower and it follows the leader keeping the prescribed formation structure. Both aircraft models are nonlinear. In the inner loo...
Numerical investigation of flow control over an airfoil with synthetic jets and its optimization Akçayöz, Eray; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2008) In this work, an active flow control method is studied numerically by using a synthetic jet over a NACA 0015 airfoil. Unsteady, turbulent flows over the NACA 0015 airfoil are computed using a Navier-Stokes solver. The Spalart-Allmaras turbulence model is employed in all computations. Unsteady flow solutions are computed in parallel using Parallel Virtual Machine library routines in a computer cluster. The synthetic jet is implemented to the flow solver as a boundary condition. Response Surface Methodology i...
Improved torque and speed control performance in a vector-controlled PWM-VSI fed surface-mounted pmsm drive with conventional P-I controllers Büyükkeleş, Ümit; Ersak, Aydın; Department of Electrical and Electronics Engineering (2012) In this thesis, high performance torque and speed control for a surface-mounted permanent magnet synchronous machine (PMSM) is designed, simulated and implemented. A three-phase two-level pulse width modulation voltage-source inverter (PWM-VSI) with power MOSFETs is used to feed the PMSM. The study has three objectives. The first is to compensate the voltage disturbance caused by nonideal characteristics of the voltage-source inverter (VSI). The second is to decouple the coupled variables in the synchronous...
Robust Model Following Control Design for Missile Roll Autopilot Gezer, R. Berk; Kutay, Ali Türker (2014-07-11) This paper presents a robust model following control method augmented with error integration and Luenberger observer for anti-air missile roll autopilot designed using optimal control laws. The design is shown to be robust to external disturbance, noisy measurements and sensor lags by frequency domain analysis. The regulation performance of the controller is presented by simulations.
