Özet:

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.
